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. The document was also submitted to the Security Council through the United Nations secretary-general.
An OPCW fact-finding mission determined that "chlorine was released from cylinders by mechanical impact in the Al Talil neighborhood of Saraqeb" on February 4, the statement said. "Among other things, these conclusions are based on the presence of two cylinders, in which, as stated, previously contained chlorine; eyewitness testimony; samples taken from the environment and indicating the presence of chlorine, which is unusual for the surrounding area; data on patients referred to medical institutions for help after the incident, which had the signs and symptoms of exposure to chlorine and other toxic chemicals", said Wednesday the press service of the OPCW. Only Syrian government forces are known to have helicopters.
The incident is by no means the worst chemical weapons attack during the seven-year civil war, but it led to 11 people being treated for breathing difficulties.More news: Senate panel poised to recommend Gina Haspel's confirmation

Following delays, the OPCW was allowed to access the Douma site where it gathered more than 100 environmental samples.
But Syria and Russian Federation have accused Syrian volunteer rescue workers of staging shocking video footage of the alleged attack at the behest of the United States.
In a brief statement Ahmet Üzümcü, the head of OPCW, said: "I strongly condemn the use of toxic chemicals as weapons by anyone, for any reason, and in any circumstances". But, the OPCW confirmed the use of chemicals in Syria in February.More news: Democrats to force vote Wednesday on net neutrality
