A recurring question in the context of the investigation by the Organisation for the Prohibition of Chemical Weapons (OPCW) into the use of chlorine in the attack against Douma on 7 April is whether chlorine is actually a chemical weapon (CW).
The simple answer is ‘yes’ if the chemical element is released as method of warfare, an act of terrorism, or any other deliberate act intended to harm or kill a person or animal.
There are two elements in the Chemical Weapons Convention (CWC) to bear in mind, namely the definition of a CW and the three Schedules (or lists with chemicals), which are annexed to the convention.
Definition of a chemical weapon under the CWC
Most toxic chemical are potentially dual-use. Moreover, the CWC wishes to cover not only yesterday’s and today’s toxic chemicals but also the ones that may be developed in the future. To this end, the CWC uses the so-called General Purpose Criterion (GPC): not the toxic chemical as such is prohibited; however, the purposes to which it may be applied are.
In this context it is useful to know that the treaty’s default condition is prohibition. In other words, all usage of toxic chemicals is prohibited unless for purposes that are not-prohibited (note the negative formulation). The CWC considers only four non-prohibited purposes.
Thus Article II, 1 states:
1. “Chemical Weapons” means the following, together or separately:
(a) Toxic chemicals and their precursors, except where intended for purposes not prohibited under this Convention, as long as the types and quantities are consistent with such purposes; […]
Here one can see that any toxic chemical is defined as a CW, except where intended for purposes not prohibited …, in which case the toxic chemical is by definition not a CW and therefore does not fall under the CWC.
Article II, 2 defines ‘toxic chemical’ as
‘Any chemical which through its chemical action on life processes can cause death, temporary incapacitation or permanent harm to humans or animals. This includes all such chemicals, regardless of their origin or of their method of production, and regardless of whether they are produced in facilities, in munitions or elsewhere’.
In other words, this definition clearly bears on chlorine.

From September 2014 on several reports have alleged chlorine use by the Islamic State in Iraq and the Levant (ISIL) in Iraq. The claims began shortly after the Organisation for the Prohibition of Chemical Weapons (OPCW) had released its first report on its investigation into the chlorine attacks in Syria earlier in the year. In a politically highly charged atmosphere in which supporters and opponents of the regime of President Bashir al-Assad use any incident to blame insurgent forces of atrocities or call for regime change, one must necessarily view accusations of chemical warfare with a healthy dose of scepticism. This is particularly the case if allegations disappear as quickly as they surface.
However, during the autumn of last year there was some consistency in the albeit irregular reports. Furthermore, on 10 February, OPCW Director-General Ahmet Üzümcü confirmed that the Iraqi authorities had notified the OPCW of chlorine gas attacks against Iraqi soldiers. At present it is not known which steps, if any, the OPCW will undertake with regard to these allegations.
Last October I described how al Qaeda in Iraq (AQI), a precursor organisation to ISIL, applied chlorine in a campaign of car bombings between October 2006 and June 2007. While many people in the vicinity of the detonation required medical treatment for exposure to the agent, nobody was actually killed by the gas. This posting looks into the various allegations of insurgent chlorine attacks in Syria and Iraq since 2013.

On 4 December I addressed a workshop on Nuclear Safety, Security and WMD Non-proliferation. The event was organised by Atomic Reporters and the Vienna Center for Disarmament and Non-Proliferation (VCDNP), together with the Stanley Foundation and the James Martin Center for Nonproliferation Studies (CNS). The target audience consisted of more than 20 journalists from or working in the Middle East.
My presentation ‘Responding to chemical weapon use in Syria’ addressed the allegations of chemical weapon (CW) use in Syria since early 2013 and the international CW disarmament operation over the past 15 months.
The audience’s reactions at times illustrated how sensitive the question of CW remains in the Middle East. When people are forced outside their comfort zone offered by established reference frameworks, regional security discussions quickly become tense. If ever serious progress is to be made on the idea of a zone free of non-conventional weapons in the Middle East, preparing a common reference framework for the participants in the debates—particularly civil society constituencies who must prepare the ground to make proposed solutions politically and socially acceptable—will be an unescapable task.
Lale Kemal, a Turkish journalist, captured the exchanges very well in a piece for the Daily Zaman on 8 December. If she leaves you with the impression that the discussions were not just intense, but also most stimulating, then I can confirm they were.
Middle East’s ‘unique’ status on chemical weapons
A colleague from a Middle Eastern country reacted sharply when a speaker in a recent workshop in Vienna used the term “Muslims” in some of his references to the countries in the region during his presentation on the issue of chemical weapons. The colleague urged him to use the names of the countries instead of generalizing them with their affiliation to Islam. The topic of chemical weapons is a sensitive one. Jean Pascal Zanders, director of The Trench — a website specializing in reporting on chemical weapons — told the workshop audience in Vienna that with the exception of the First Indochina War, all cases of major chemical warfare after World War II have taken place in the Middle East.
Yet this journalist’s reaction to the speaker in his usage of the term “Muslims” does not change the reality that — in the words of Mehmet Dönmez, head of Turkey’s Religious Affairs Directorate — around 900 Muslims per day are killed by fellow Muslims around the world, including in the Middle East. Nevertheless, the topic of the workshop for journalists from the Middle East, held in Vienna between Dec. 3-5, was on nuclear safety, security and WMD non-proliferation. WMD is short for “weapons of mass destruction,” which are chemical, biological and nuclear weapons — the deadliest weapons that have so far been developed by humankind.
The workshop was sponsored by the United Arab Emirates (UAE), along with nongovernmental organizations the James Martin Center for Nonproliferation Studies (CNS), the US-based Stanley Foundation and Vienna-based Atomic Reporters. The event was hosted by the Vienna Center for Disarmament and Non-Proliferation (VCDNP). It was a follow-up to the first workshop, which was held in I.stanbul in June of this year in cooperation with I.stanbul’s Okan University.
Going back to the topic of chemical weapons in the Middle East, Zanders from The Trench cited the known incidents of the usage of chemical weapons in the region, including Egypt during its war with Yemen in the 1950s and Iraq against Iran in 1984 during the long-lasting war between the two countries in the 1980s, as well as Iraq’s use of mustard gas against its own Kurds. Syria lately staged a sarin gas attack against its own citizens in Ghouta, near Damascus. Syria’s chemical weapons were destroyed under a deal it struck with some world powers, yet it is unclear whether the country is still hiding some of its chemical weapons stockpile.
Meanwhile, Israel is the only country in the Middle East widely known to possess nuclear weapons, even if it neither denies nor confirms their existence. Iran is accused by the international community of seeking to develop nuclear weapons under the guise of developing nuclear energy power plants.
Dr. Chen Kane from the CNS strengthened Zanders’ assertion, saying during the workshop that, concerning cases of the usage of chemical weapons as well as their possession, the region is unique. According to her, in the Middle East, all three categories of weapons of mass destruction — chemical, biological and nuclear — have been pursued by different states and chemical weapons have even been used in the region on several occasions. She mentioned fundamental ongoing territorial, religious, ethnic and other disputes that underline that the reality of WMDs and that the acquisition of WMDs in the region is interrelated and politically and security-motivated. Out of the seven violations of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), Dr. Chen said five are from the Middle East — Iran, Iraq, Libya, Syria and Egypt. This situation illustrates the risk associated with nuclear programs in unstable countries and war zones. It is unclear if any Middle Eastern country possesses biological weapons. The unstable nature of the Middle East also carries the risk of terrorist groups obtaining WMDs.
In February 2015, the Ja?far al-Tayya-r brigade and the al-Nusra Front gained control of the al-Kibar site (also called Dair Aizour) in Syria, where a nuclear reactor believed to have been under construction was destroyed by Israel during an air raid in 2007. According to Zanders, the Islamic State in Iraq and Syria (ISIS) — a terrorist group against which US-led Western and Arab coalition forces are currently carrying out an air campaign in both Iraq and Syria — has not obtained WMDs.
Turkey, a NATO member and a neighbor to the Middle East, came under criticism a long time ago for using white phosphorus — a kind of a chemical weapon — against militants from the outlawed Kurdistan Workers’ Party (PKK). However, Zanders stated that such allegations from the PKK have never been confirmed by international organizations addressing WMDs.
The absence of a security framework or organization in the Middle East — where there is no regional conventional arms control culture — to mitigate the danger of WMDs poses a great threat to the region in particular and the world in general.
In a letter dated 7 July 2014 Iraqi Ambassador to the United Nations Mohamed Ali Alhakim notified UN Secretary-General Ban Ki-moon that ‘armed terrorist groups’ had entered the Muthanna complex on 11 June. The next morning a project manager observed them looting of some equipment via the camera surveillance system before the ‘terrorists’ disabled it. The document, as cited by the Associated Press, explicitly referred to the capture of bunkers 13 and 41, two locations still holding chemical weapons (CW) so severely damaged during the 1991 war to liberate Kuwait that until today they could not be disposed of in a safe way.
The capture of two CW storage bunkers at Muthanna by Islamic State of Iraq and the Levant (ISIL, now shortened to Islamic State) has raised fears of chemical warfare in Iraq as well as Syria. The insurgent grouping’s habitual resort to extreme violence in combat, its strict upholding of Sharia law, and uncompromising attitude towards ‘non-believers’ leave many a commentator convinced that it will stop at nothing in its pursuit of the Islamic state.
Analysis of documents relating to the dismantlement of the Muthanna complex in the 1990s and the subsequent monitoring of the site however demonstrates that it would be all but impossible for ISIL to acquire and use Iraq’s former CW, or for that matter, the toxic residues of warfare agents.
Should the ISIL fighters still find sarin, then the probability of the agent’s degradation below any useful degree of purity is extremely high. An additional 20 years have passed since the UNSCOM Chemical Demolition Group sealed the storage bunkers. Mustard agent is far more stable, but both UNSCOM and UNMOVIC reported significant degradation. 155mm artillery rounds were found to contain hydrogen gas and other breakdown products leading to considerable internal pressure. Moreover, the thick-skinned shells proved particularly difficult to penetrate and drilling risked ignition of the built-up gases.
UNSCOM selected two bunkers at Al Muthanna for their solid structure. After completion of destruction operations, it sealed the structures. They blocked off all entrances with two brick walls and a 5cm layer of tar in between them. A third brick wall was erected at a distance of 1 metre from the second wall and the space in between was filled with reinforced concrete. Together, the overall thickness of the entrance seals amounts to 1.5 metres. The hole at the top of bunker 13 containing the sarin rockets and precursor chemicals from a US bomb in 1991 was closed by filling the whole inner room with soil through that hole and then plugging it with reinforced concrete.
Any penetration of the bunker by ISIL fighters would require major dismantling and rubble removal, all the while not knowing the exact location of the toxic chemicals, propellants and explosives and facing potential exposure to contaminated soil or air. Even the Organisation for the Prohibition of Chemical Weapons (OPCW) is still considering how it might proceed to determine the bunker’s exact contents.
More technical details on the state of Iraq’s former CW and tables on the contents of the bunkers are in an article I wrote for the August edition of CBRNe World. Registration may be required, but it is for free.

I am not the only person who is concerned by the banalisation of tear gas as a riot control agent. Over the past few years, the intensity with which such agents have been used has increased markedly, to the point that whole sections of cities now routinely become saturated with the toxic chemicals. In particular Michael Crowley of Bradford University’s Non-Lethal Weapons Project has published studies on the fast technological development and growing global markets of riot control agents and their delivery systems: one in collaboration with the Omega Research Foundation, and one, co-authored with Dana Perkins, then expert of the 1540 Committee, for the Biochemical Security 2030 Project, University of Bath. Likewise, the Physicians for Human Rights issued a report in 2012 on the Bahrain government’s indiscriminate use of tear gas, and in 2013 another one on tear gas excesses in Turkey.
The recent massive use of tear gas by a highly militarised local police force to quell riots in Ferguson, Missouri, has drawn renewed attention to a weapon that the Chemical Weapons Convention bans as a tool of warfare.
Anna Feigenbaum has just published a historical overview of tear gas in The Atlantic, starting with the fist use of a chemical weapon by the French in World War 1 exactly 100 years ago this month.
Perhaps most striking is her compilation and mapping of global tear gas use during 2013 (my screenshot):
A PDF printout of the incidents she has listed runs for 19 pages.
Alas, if a riot control agent is used as a tool for law enforcement or domestic riot control purposes, then the Chemical Weapons Convention does not consider it as a chemical weapon and therefore falls outside its scope of application.

Since my last update on the elimination of Syria’s chemical weapon (CW) capacities in May, all precursor chemicals have finally left the country. Some have been shipped to facilities in Finland and the USA, where they are in the process of being destroyed. The United Kingdom meanwhile completed the destruction of 190 tonnes of chemicals at an incinerator in Ellesmere Port.
As of 7 August, 74.2% of Syria’s entire stockpile of chemical warfare agent precursors have been destroyed. Other chemicals are meanwhile being neutralised on board of the US vessel Cape Ray in the Mediterranean, and the resulting reaction mass will eventually be commercially incinerated too.
The Organisation for the Prohibition of Chemical Weapons (OPCW) is gradually slipping off the radar screen of international media. The huge pressure of safely evacuating the precursor chemicals from the war-torn country now removed, the organisation can slowly return to its more familiar role in the background of international politics: monitoring compliance with the Chemical Weapons Convention (CWC) and resolving any outstanding issues. Syria will increasingly become more integrated as a ‘normal’ member of the OPCW. This, however, does not mean that the OPCW will relax its efforts to achieve full accounting of its chemical warfare programmes, clarification of allegations of CW use, or complete destruction of all relevant declared facilities. Syria’s recurring amendments to its initial declaration of 23 October 2013 demonstrate the grinding, but nonetheless steady progress the OPCW is making.
Two new elements (at least to outsiders) have surfaced over the past couple of weeks: Syria’s presentation of a destruction plan for abandoned chemical weapons (ACW) and the declaration of a CW production facility dedicated to ricin manufacture.
Re-hexamination of Syria’s sarin
The UN Secretary-General’s latest monthly progress report on the elimination of Syria’s chemical warfare capabilities refers to Syria’s submission on 14 July of a destruction plan for two sarin-filled munitions. Syria denies ownership of these CW and has therefore declared them as ACW.
The two munitions were recovered after the CW attack at Jobar, an eastern suburb of Damascus, on 24 August 2013 (i.e., three days after the Ghouta chemical attacks). Four days later, Syria notified the UN Secretary General of the use of an improvised explosive device (IED) releasing a foul and strange odour. The UN team investigating alleged CW use visited the site on 29 September. It was unable to examine the place of impact or recover munition fragments, because mine clearing operations had completely corrupted the surroundings. Syrian officials handed over IED fragments and contaminated soil samples, which they claimed came from the incident site. For obvious reasons, the UN team could not certify their chain of custody.
According to the Final Report by the UN Mission (p. 65), the investigative team ‘was also presented with two metal canisters discovered by Government soldiers during the offensive operations in Jobar on 25 August 2013 in the immediate aftermath of the incident and in close vicinity of the site of the alleged incident’. These were said to be identical to ones used in the chemical incident the day before. Made of steel sheeting of 1mm thickness, the plates were bent and welded together manually at a sub-industrial standard. The canisters nevertheless revealed a high degree of expertise with the electric welding process. The UN investigators were also able to establish that ‘a detonator and a coiling of the detonating cord, acting as a booster, composed the fire train, electrically initiated’. They had an internal fill capacity of up to approximately 4 litres (see figure below). The two metal canisters are the ACW Syria declared to the OPCW. (This description corrects the suggestion in my posting of 26 May that the two ACW were Volcano rockets. The claim that Syria did not declare any Volcano rockets as CW still stands, however.)
Analysis of their contents by the OPCW confirmed sarin as their payload. Moreover, the filling displayed all the characteristics of sarin as produced by the Syrian government, the principal telltale sign being the presence of hexamine (hexamethylenetetramine). Since its presence in samples was first reported by the UN investigative team last September in relation to the Ghouta attack and the OPCW later released that Syria had declared 80 metric tonnes of the chemical in connection with sarin production, there has been furious speculation as to its exact role. In a recent analysis focussing explicitly on the role of hexamine, UK-based CW expert Daniel Kaszeta argued that the Syrians used the compound as an acid scavenger in the final reaction of their rather unique sarin production process. Reacting DF (methylphosphonyl difluoride) with isopropanol yields sarin and hydrofluoric acid, the latter being a toxic and extremely corrosive gas that would have quickly damaged the production and agent filling installations. Hexamine binds this acid, and does so more efficiently than other amino compounds.
However, recent discussions with officials from some Western states indicate two other roles of hexamine, namely as catalyst and stabiliser. The catalyst function is probably closely tied to the acid scrubber role. In an e-mail exchange today, Ralf Trapp, a chemist and consultant to the OPCW, confirmed that hexamine increases the yield of the chemical reaction by pulling the equilibrium between the precursors and reaction product (sarin) in favour of the latter. As a result, the sarin concentration receives a significant boost, possibly up to 60%. This degree of purity is considerably higher than the yields achieved by Iraq in the 1980s.
As a stabiliser, hexamine probably allowed the Syrians to store freshly produced sarin for days, if not several weeks. This understanding is more compatible with views before the civil war that Syria’s CW served strategic deterrence. Munitions declared to the OPCW last autumn also seem to validate those views. Initiating the final reaction shortly before use, as was the case in Iraq, would have undermined this doctrinal role. The insight also raises fresh questions about the curious White House claim last August that the United States had observed Syrian preparations for three days prior to the Ghouta attacks.
Strictly speaking, the chemical analysis of the sarin in the two ACW confirms beyond any doubt that the nerve agent was produced by means of the same process as the one used by the Syrian government. The distinctive signature, however, cannot exclude the possibility that insurgents might have captured some CW. Western officials tend not to give much credence to this hypothesis.
Castor beans: cancer research, castor oil, or ricin?
The latest monthly progress report also reveals that on 14 July Syria submitted yet another amendment to its initial declaration. The document lists a dedicated ricin production plant. As a weapon the toxin is banned under both the Biological and Toxin Weapons Convention (BTWC) and the CWC. The CWC requires the verified destruction of CW production facilities, but the amendment claims that it is located in an area not under government control. It also states that the entire quantity of ricin produced was eliminated prior to the entry into force of the CWC for Syria. If correct, then Syria need not declare its past toxin weapon holding. CW disarmament in Syria, however, is hardly a normal operation. As with its claimed destruction of 200 tonnes of mustard agent early in 2013, the OPCW must investigate those statements to ascertain that the country is not hiding any residual CW.
This progress report was the first to publicly mention ricin production. Last April concerns about the toxin had already filtered out of the United Nations, but they have thus far remained a relatively low-level matter at the OPCW. This was in part a consequence of the high-priority preoccupation with getting the precursor chemicals out of Syria, and in part because nothing seems to indicate that the country presently has ricin weapons. Questions remain nonetheless.
Syria apparently cultivated castor oil plants (Ricinus communis) on several tracts the size of football fields. In itself, this is no so unusual as the oil makes for an excellent lubricant for heavy engines, such as those in military lorries. However, Syria’s initial explanation referred to cancer research and treatment, which was wholly implausible in view of the minute quantities of ricin required for research. Castor oil also lacks any medicinal value to cure cancer. It was used to deliver some chemotherapy drugs to tumours, but occasional side effects, such as allergic reactions, have led to the adoption of alternatives. Starting in the 1980s, Texas Tech University and Texas Tech University Health Sciences Center conducted long-term research on the oncological application of genetically modified ricin to kill diseased cells. According to a press release of October 1998, ‘just two acres of land, given the right castor seed, could produce enough ricin to meet the world’s pharmaceutical supply need for cancer treatment’. Ricin is also being investigated in relation to neurological degenerative disorders and in the treatment of intractable painful neuropathies. It is rather hard to think of Syria as a global supplier of medicinal ricin many times over.
This leaves the question of ricin as a weapon. Ricin is an instrument of choice for assassinations, as befell Bulgarian dissident writer Georgi Markov in London in 1978. More recently clumsy attempts to send ricin-filled letters to hated persons, including President Barack Obama, have also put the spotlight on the agent. Since the First World War many states considered ricin as a possible tool of warfare, but they have never incorporated it as a standard agent into their chemical and biological warfare arsenals. Despite the military attractiveness of its toxicity, the toxin poses several serious problems in relation to large-scale production, longer-term storage (unless turned into a solid), and dissemination techniques. While none of these problems are insurmountable, the net effect is that the agent is more cumbersome to weaponise or less effective on the battlefield than alternatives.
Right now the reason behind Syria’s declaration of a CW production facility exclusively dedicated to ricin manufacture remains murky. On the one hand, in view of the many publicly available accounts describing the many difficulties of producing and especially storing the toxin in free state for longer periods of time, it almost seems implausible that Syria would have embarked on a major ricin weapon programme. Interestingly, several Western officials I recently spoke to tend to discount public Israeli reports on Syria’s ricin programme. The annual US State Department report on arms control treaty compliance for 2014 dropped the reference to ricin-based biological weapons in the BTWC section and does not mention the toxin in the separate CWC compliance report. The 2013 treaty compliance document still stated: ‘In 2004, Israel’s Intelligence and Terrorism Information Center said in a report on Syria that the Scientific Studies and Research Center had been developing ricin-based biological weapons’.
On the other hand, if the Syrian factory was indeed dedicated to the production of oil or lubricants, the possibility exists that it used a cold hydraulic pressing technique, in which case 1–5% by weight of ricin might remain in the resulting mash. A fact sheet on ricin by the OPCW Science Advisory Board (SAB) released in February 2014 notes that castor oil production plants are not subject to Schedule 1 inspections under Article VI of the CWC. The SAB therefore recommended that the Director-General encourage National Authorities in producing countries to promote hot pressing and other techniques that ensure inactivation of residual ricin in the waste mash. In other words, the Syrian amendment might reflect a compromise with the OPCW to remove any ambiguity about the purpose of the ricin resulting from a particular production process in view of the need for absolute certainty that all aspects of the country’s CW programme have been eliminated. A future oil-extraction plant using a process that inactivates residual ricin could then be constructed without the need for long-term verification modalities for that installation.
A possible explanation for the ricin factory declaration for sure, but more details are required to confirm the scenario. To be continued.
And the destruction of mustard agent?
As I reported in May, OPCW inspectors were looking into Syria’s claim earlier this year that it had destroyed some 200 tonnes of mustard agent in the spring of 2013. They are still trying to obtain further documentation substantiating these destruction operations. Onsite inspections of the disposal sites are still pending before this particular file can be closed.
[Cross-posted from The Trench.]
Syria has now missed about every single deadline since it was unable to move the Priority 1 chemicals out of the country by the end of last year. These even include renegotiated time frames and the self-imposed final date of 27 April. One more fixed date is pending: 30 June, by which time all precursor chemicals should have been neutralised.
It would now seem that the world will sigh with relief if everything is aboard the Danish and Norwegian freighters by the end of next month. US officials envisage 60 working days to neutralise the volume of precursor chemicals and hydrolyse the mustard agent on board the US ship Cape Ray. The end of this mission could be pushed back even further if factors such as bad weather or sea states exceeding safety standards interrupt activities. In addition, the original schedule foresaw incineration of the reaction mass by the end of 2014. However, one of the companies selected by the Organisation for the Prohibition of Chemical Weapons (OPCW), Finland’s Ekokem, requires at least nine months. This potentially pushes completion of the disarmament tasks agreed in the US-Russian framework agreement of September last year into the second quarter of 2015. Consequently, the disarmament mandate established by UN Security Council resolution 2118 (2013) can be expected to remain in place at least as long.
Similar delays affect the final destruction of former CW production facilities (CWPF). Different interpretations about the perimeter of several CWPFs block consensus decision-making on the formal destruction plan in the Executive Council of the OPCW, and hence progress in the field.
Finally, concerns have emerged whether Syria has declared its entire CW stockpile. In particular, the country has claimed destruction of 200 metric tonnes of mustard gas in March 2013, but initially failed to declare this to the OPCW.
Remaining precursor chemicals
Syrian authorities have consistently claimed that heavy fighting at key sites and high security risks along the transportation routes make it all but impossible to transfer the precursor chemicals to the port of Latakia within the set deadlines. The Joint OPCW-UN Mission has tended to confirm these security assessments. It has also reported shelling into Latakia in March and intensive combat operations around the final storage site.
According to the 7th monthly report submitted to the UN Security Council on 25 April, 96.45% of declared Priority 1 chemicals and 81.09% of declared Priority 2 chemicals had been moved onto the Danish vessel Ark Futura and the Norwegian freighter Taico respectively. Combined they amounted to 92.03%. The remaining 8%—about 100 metric tonnes of precursors—consisted of
- Priority 1 chemicals:
- B salt (N (2-chloroethyl)-N-ethyl propan 2 amine salt)
- DF (methylphosphonyl difluoride)
- Priority 2 chemicals
- Butan-1-ol (alcohol)
- HCl (hydrogen chloride)
- HF (hydrogen fluoride)
On 20 May, the OPCW–UN Joint Mission confirmed the destruction of all isopropanol. (It should be noted that ‘B salt’ did not figure in the initial list of precursors and was included in one of the revised declarations by Syria. It is possible that a declaration error was made concerning ‘BB salt’.)
The 7.2% of chemicals that must still be shipped out remain trapped at Al Sin. Very little is known about the military site, except for its identification as a CW production facility in the 3rd monthly report of last December (Annex, paragraph 15). ‘Al Sin’ features in a few combat reports by insurgent factions published to the internet on 20 March, and are described as depots or an airport. Some press accounts suggest that the chemicals are at an airbase.
Battalion 559 of the Syrian armed forces holds a storage base that fits the descriptions. It is located about 63km to the northeast of Damascus along a major road travelling from the Adra suburban area in the general direction of Palmyra (Tadmur). About 14km to the south of Al Sin lies the Sayqal Military Airbase, which also houses several ammunition storage installations.
Al Sin has two major access routes (presumable the aforementioned main road going either northeast or southwest) and a secondary road travelling through the mountains. At present, the main access routes are unusable because they are controlled by insurgents or within easy targeting range of their heavier weaponry. The secondary road is impractical, considering that the DF has been transferred into large 2000-litre reinforced containers and the highly dangerous and volatile HF is contained under pressure in industry-standard cylinders. Transport in a large, escorted convoy along a mountainous track not only runs a high risk of accidents, the surroundings also offer many opportunities for ambushes. The Syrian army is currently mounting major military operations to clear (one of) the two principal routes out of Al Sin. Once achieved, the evacuation of the final precursors to Latakia is expected to be completed shortly afterwards.
Destruction of CW production facilities at an impasse
Political blockage over the destruction of Syria’s twelve CWPFs prevents progress on an important dimension of the elimination of the country’s chemical warfare capacity. The Chemical Weapons Convention (CWC) refers to CWPFs in many articles and sections of the Verification Annex. Article II, 8 defines it in terms of equipment for producing or filling certain types of chemicals and buildings that house such equipment. They must be irreversibly destroyed under a detailed destruction plan, although some buildings can be converted under strict conditions to purposes not prohibited by the convention. Despite Syria’s request, the Executive Council of the OPCW has refused to authorise conversion of some facilities.
In contrast, CW storage facilities (CWSF) are discussed only in the Verification Annex, Part IV(A) in relation to the presence of CW, their verification and destruction. A party to the CWC must declare a CWSP’s name, exact coordinates and a detailed site diagram, including a boundary map and the location of bunkers/storage areas within the facility. It must also provide a detailed inventory of the CW they contain. No treaty provision, however, demands the destruction of CWSFs.
Syria has apparently five underground structures, tunnels shaped in the form of a staple. They comprise three major sections. Each of the two extremities offers entrance to the complex. However, only one of the arms is the actual CWPF; the two other sections Syria has declared as storage sites. Following extensive discussions with OPCW technical staff and onsite visits at the end of March, a CWPF destruction plan was proposed to the Executive Council, which it rejected. The United States and other members of the Western Europe and Other States Group represented on the Executive Council argued that the storage areas form an integral part of the production site, and that therefore Syria’s circumscription of the CWPFs is incomplete. In addition, the argument has been put forward that via a network of tunnels they link up to other parts of a larger military complex.
It is difficult to see how the impasse can be overcome soon. The Executive Council habitually decides by consensus. If the United States and its partners press for a vote, they are by no means certain of gaining a majority. Even if they do, there may be ramifications in other areas of treaty implementation further down the road. Syria, for its part, has adopted a very assertive posture since becoming an OPCW member last October and is unlikely to budge on anything that does not represent a formal, unambiguous obligation under the CWC or without pressure from Russia. The current frosty relations between Moscow and Washington are not helpful either.
Did Syria declare all?
Over the past month or two several questions have arisen as to whether Syria declared its full chemical warfare capacity. They are in part due to the recent attacks with barrel bombs allegedly containing chlorine canisters, and in part to the amendments to its formal declarations to the OPCW. The latter are the result of normal verification routines by OPCW staff, which it undertakes for all parties to the OPCW. Analysis of declarations and onsite inspections often lead to the discovery of inconsistencies, contradictions or even missing information, which yield lists of questions and issues that the state party must resolve. Syria is no exception, and a significant new amendment to earlier declarations is expected in the near future. Although it will not contain new types of chemicals, there will be variations in the volumes of declared precursors without much changing the overall total of 1,300 metric tonnes. In contrast, it will include a thus far undeclared CW research centre near Damascus. (Readers of this blog will recall that the Executive Council and UN Security Council decisions of 27 September compel Syria to declare research facilities, even though this is not required by the CWC.)
A initial team of 8 OPCW inspectors left for Syria on 2 May and they were joined by an additional 5 personnel on 12 May to investigate the chlorine attack allegations. They can have access to the one site where the government has claimed that the rebels used a chlorine weapon, but until now have been refused entry into the rebel areas. Negotiations with insurgents to enable the safe transit of the precursor chemicals to the port of Latakia or for OPCW-UN Joint Mission staff to have access to sites in rebel-controlled territory are conducted through the office of Lakhdar Brahimi, the Joint Special Envoy of the United Nations and League of Arab States for Syria. While the office continues to function, Brahimi’s resignation on 13 May, effective at the end of the month, implies the loss of a lot of political clout with the insurgents. It’s impact on the disarmament process is unclear for the time being, but the convoys transporting the precursor chemicals and the OPCW–UN Joint Mission may face growing security and safety challenges if the current lack of progress continues for any significant length of time. Future investigations of alleged used of CW may also be compromised.
Another element that tends to contribute to the unease about Syria’s truthfulness is the fact that until today the government has not declared owning any of the Volcano rockets believed to have delivered sarin nerve agent against the Ghouta district last August. It did report two such missiles, but stated that it had found them and that it was not their possessor. Many countries and observers blame the Syrian military for the Ghouta attacks and other chemical strikes.
Finally, the questions if Syria has declared all its ‘weaponised’ warfare agents revolve around whether it has irreversibly disposed of about 200 metric tonnes of mustard gas. Syrian officials claim that the stock was destroyed at three sites in March 2013, around the time of the chemical attacks in Khan al-Assal near Aleppo and several months before the Ghouta sarin strikes. (No allegation of a mustard attack has so far been recorded.) Interestingly enough, Syria apparently mentioned these destruction activities before or during the US-Russian bilateral negotiations in Geneva last September, but the issue has only been picked up more recently. The Syrian government has now supplied the OPCW with details of these operations, which still require confirmation. OPCW inspectors plan to verify the claim and the veracity of its particulars by means of interviews, record analysis and on-site sampling. UNSCOM inspectors in Iraq during the 1990s occasionally had to resort to similar methodologies to determine whether the claimed volume of agent destroyed without international supervision corresponded to reality. Syria formally declared 20.25 metric tonnes of mustard agent (an amount relatively small compared to the overall volume of declared nerve agent precursors), which will be hydrolysed on board the Cape Ray. Inevitably, the episode has raised concerns among some OPCW members about possible undeclared ‘weaponised’ nerve agents.
More to follow over the next weeks, I am sure.
Postscript: Two hours after posting this contribution, the OPCW published an updated report on the status of CW disarmament in Syria.
