Reports of the accident were circulated at the time; however, no details were released by the Syrian government, and there were no hints of an Iranian connection. The report comes on the heels of criticism leveled by the Syrians at the United States, accusing it of spreading "false" claims of Syrian nuclear activity and cooperation with North Korea to excuse an alleged Israeli air incursion over the country this month. According to globalsecurity.org, Syria is not a signatory of either the Chemical Weapons Convention (CWC), - an international agreement banning the production, stockpiling or use of chemical weapons - or the Comprehensive Nuclear Test Ban Treaty (CTBT). Syria began developing chemical weapons in 1973, just before the Yom Kipper War. Globalsecurity.org cites the country as having one of the most advanced chemical weapons programs in the Middle East.
