Destruction of Syria's chemical weapons
The destruction of Syria's chemical weapons began with several international agreements that were arrived at with Syria, with an initial destruction deadline of 30 June 2014. United Nations Security Council Resolution 2118 imposed on Syria responsibilities and a timeline for the destruction of its chemical weapons and chemical weapons production facilities. The Security Council resolution incorporated and bound Syria to an implementation plan enacted in an Organisation for the Prohibition of Chemical Weapons (OPCW) Executive Council Decision. On 23 June 2014, the last declared chemical weapons were shipped out of Syria for destruction. The destruction of the most dangerous chemical weapons began at sea aboard the Maritime Administration Ready Reserve Force vessel CAPE RAY crewed with U.S. civilian merchant mariners. It took 42 days aboard ship to destroy 600 metric tons of chemical agents that would have been used to make deadly Sarin and Mustard Gas.The impetus toward destroying Syria's chemical weapons began with a 9 September 2013 rhetorical suggestion by U.S. Secretary of State John Kerry that Syria turn over all of its chemical weapons within a week. At the time, the U.S. and France headed a coalition of countries on the verge of carrying out air strikes on Syria in response to the 21 August 2013 Ghouta attacks. The suggestion received a positive response from Russia and Syria, and U.S.–Russian negotiations led to the 14 September 2013 ""Framework for Elimination of Syrian Chemical Weapons,"" which calls for the elimination of Syria's chemical weapon stockpiles by mid-2014. Following the agreement, Syria acceded to the Chemical Weapons Convention and agreed to apply that convention provisionally until its entry into force on 14 October 2013. On 21 September, Syria ostensibly provided a list of its chemical weapons to the OPCW, before the deadline set by the framework.On 27 September, the Executive Council of the OPCW adopted a decision, ""Destruction of Syrian Chemical Weapons,"" a detailed implementation plan based on the U.S./Russian agreement. Later on 27 September, the UN Security Council unanimously passed United Nations Security Council Resolution 2118, incorporating the OPCW plan and making it binding on Syria. A joint OPCW-UN mission will supervise the destruction or removal of Syria's chemical arms, while its Director-General is charged with notifying the Executive Council regarding any delay in implementation. The Executive Council would decide whether the non-compliance should be reported to the Security Council, which is responsible for making certain Syria fulfills its commitments under Resolution 2118.OPCW began preliminary inspections of Syria's chemical weapons arsenal on 1 October 2013, and actual destruction began on 6 October. Under OPCW supervision Syrian military personnel began ""destroying munitions such as missile warheads and aerial bombs and disabling mobile and static mixing and filling units."" The destruction of Syria's declared chemical weapons production, mixing, and filling equipment was successfully completed by 31 October deadline. The destruction of the chemical weapons fell well behind schedule. The entire chemical weapons stockpile had been scheduled to be completely removed from the country by 6 February 2014. Only on 23 June 2014, had Syria finished shipping the remaining declared chemicals. On 18 August 2014, all of the most toxic chemicals had been destroyed offshore. Western officials such as British Ambassador Mark Lyall Grant have expressed concerns about the completeness of Syria's disclosures, and believe the OPCW mission should remain in place following the removal of chemical weapons until verification tasks can be completed.Chlorine, a common industrial chemical, is outside the scope of the disarmament agreement; however, its use as a poison gas would violate the Chemical Weapons Convention, which Syria joined in 2013. Various parties, including Western governments, have accused Assad of conducting illegal chlorine attacks in 2014 and 2015. A late disclosure in 2014 regarding Syria's ricin program raised doubts about completeness of the government's declaration of its chemical weapons stockpile, and in early May 2015, OPCW announced that inspectors had found traces of sarin and VX nerve agent at a military research site in Syria that had not been declared previously by the Assad regime.
