Last week, it said it found"reasonable grounds to believe" that a Syrian air force military helicopter dropped a chlorine cylinder on a Syrian town in 2018, sickening 12 people.
Last year, the team found reasonable grounds to believe that the Syrian Arab Air Force was responsible for attacks using chlorine and the nerve agent sarin in March 2017 in the town of Latamneh. The investigative team was established after Russia blocked the extension of a joint investigation mechanism set up by the United Nations and OPCW in 2015. That mechanism accused Syria of chemical weapons attacks, including unleashing sarin in an aerial attack on the town of Khan Sheikhoun in April 2017 that killed about 100 people.
