The Chemical Weapons Convention comprehensively prohibits the use, development, production, stockpiling, and transfer of chemical weapons. 

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

Since May 2014, the OPCW has deployed the FFM in numerous occasions to the Syrian Arab Republic and outside of Syria and has kept States Parties informed of its work. The FFM interviews witnesses and obtains samples and physical evidence for analysis. 

In 2015, the OPCW Executive Council and the UN Security Council endorsed the continual operation of the FFM. 

The FFM’s findings established the facts surrounding allegations of the use of toxic chemicals as weapons in Syria and confirmed that chemical weapons had been used. The FFM’s findings were the basis for the work of the OPCW-UN Joint Investigative Mechanism (JIM), an independent body established by the UN Security Council (Resolution 2235, 7 August 2015). The JIM’s purpose was to identify the perpetrators of the chemical weapon attacks confirmed by the Fact Finding Mission. The JIM’s mandate expired in November 2017.
