The declaration contained no surprises, OPCW spokesman Michael Luhan indicated. The production facilities were "put out of commission" by airstrikes during the 1991 conflict, while U.N. personnel afterward secured the chemical munitions in the bunkers. Luhan stated at the time: "These are legacy weapons, remnants." He declined to discuss how many weapons were stored in the bunkers or what materials they contained. The weapons were not believed to be in a usable state.
