At a meeting to review the operation of the Chemical Weapons Convention (CWC), U.S. Ambassador Kenneth Ward expressed "longstanding concerns that Iran maintains a chemical weapons program" that has not been declared to the Organization for the Prohibition of Chemical Weapons (OPCW). Specifically, he cited Iran's failure to declare transfers of chemical weapons to Libya in the 1980s, Iran's undeclared stocks of riot control agent, and Iran's failure to declare all chemical weapons production facilities.
