I want to know the answer to the following question:
When did the UN Security Council order Syria's chemical weapons be destroyed?
All the background I'm provided with is that "Syria quickly welcomed this proposal and on September 14, the UN formally accepted Syria's application to join the convention banning chemical weapons, and separately, the U.S. and Russia agreed on a plan to eliminate Syria's chemical weapons by the middle of 2014.". Is that enough to answer the question?
