THE HAGUE, Netherlands —13 June 2018—The Fact-Finding Mission (FFM) of the Organisation for the Prohibition of Chemical Weapons (OPCW), confirmed in a report released today that sarin was very likely used as a chemical weapon in the south of Ltamenah, Syrian Arab Republic, on 24 March 2017. The FFM also concluded that chlorine was very likely used as a chemical weapon at Ltamenah Hospital and the surrounding area on 25 March 2017.

The conclusions for the 24 March and 25 March incidents are based on separate witness testimony, epidemiological analysis and environmental samples. The collection of information and material, interviewing witnesses, as well as analysis of samples required a longer period of time to draw conclusions.

The FFM’s report on the Ltamenah incidents has been shared with States Parties to the Chemical Weapons Convention. The report was also transmitted to the UN Security Council through the UN Secretary-General.

Background

In response to persistent allegations of chemical weapon attacks in Syria, the OPCW Fact-Finding Mission (FFM) was set up in 2014 with an on-going mandate “to establish facts surrounding allegations of the use of toxic chemicals, reportedly chlorine, for hostile purposes in the Syrian Arab Republic”.

The FFM’s mandate is to determine whether chemical weapons or toxic chemicals as weapons have been used in Syria. It does not include identifying who is responsible for alleged attacks. Attribution was part of the mandate of the OPCW-UN Joint Investigative Mechanism, set up by the UN Security Council, which expired in November 2017.

The FFM has previously confirmed with a “high degree of confidence” the use of chlorine, sulfur mustard, and sarin as weapons.

The FFM is required to study available information relating to allegations of use of chemical weapons in Syria, including information provided by the Syrian Arab Republic and others. The FFM employs investigative methods to determine if chemical weapons have been used. It interviews witnesses and obtains environmental and bio-medical samples and physical evidence for analysis.

The Organisation for the Prohibition of Chemical Weapons operates according to a strict confidentiality regime, which governs the operations of the Organisation, protects the integrity of its investigations, ensures the security of its technical experts, and determines what information can be made public.

As the implementing body for the Chemical Weapons Convention, the OPCW oversees the global endeavour to permanently and verifiably eliminate chemical weapons. Since the Convention’s entry into force in 1997 – and with its 192 States Parties – it is the most successful disarmament treaty eliminating an entire class of weapons of mass destruction.

Over 96% of all chemical weapon stockpiles declared by possessor States have been destroyed under OPCW verification. For its extensive efforts in eliminating chemical weapons, the OPCW received the 2013 Nobel Peace Prize.
