The United Nations Security Council adopted United Nations Security Council resolution 2235 (2015) on 7 August 2015, in response to use of chemical weapons in the Syrian Civil War. The resolution condemned "any use of any toxic chemical, such as chlorine, as a weapon in the Syrian Arab Republic" and expressed determination to identify and hold accountable those responsible for such acts. The resolution established a Joint Investigative Mechanism (JIM), a partnership between the United Nations (UN) and the Organisation for the Prohibition of Chemical Weapons (OPCW) . The Security Council renewed the JIM's mandate in resolution 2319 (2016) on 17 November 2016, for a further period of one year.[1]
The mandate of the JIM lapsed in November 2017, after Russia blocked the renewal of its mandate.[2]
