"UK has tabled draft decision aimed at strengthening the ban on chemical weapons. We propose the OPCW begins attributing responsibility for chemical weapons attacks in Syria. We also want action to support states to address the chemical terrorism threat. With proven technical expertise on chemical weapons the OPCW is the right body to study who is behind an attack," Johnson wrote on Twitter.
The statement followed the release of the OPCW Fact-Finding Mission's (FFM) report on chemical weapons use in Syria, which confirmed that sarin was very likely used as a chemical weapon in the south of Ltamenah, Syrian Arab Republic, on 24 March 2017. However, the document noted drawing final conclusions on the issue would require a longer period of time, due to "the collection of information and material, interviewing witnesses, as well as analysis of samples."
The claimed use of chemical weapons in Syria has become one of the main topics of the international agenda within the last several years after numerous accusations by the Syrian opposition, as well as Western countries, against Syrian government forces.
The Syrian authorities have repeatedly said that their chemical weapons stockpiles had been destroyed under the supervision of the OPCW.
