The weapons include: mustard gas, Sarin, Tabun and VX.
The Telegraph reported:
Chemical weapons produced at the Al Muthanna facility, which Isis today seized, are believed to have included mustard gas, Sarin, Tabun, and VX.
Here is the CIA’s file on the complex.
Quote Stockpiles of chemical munitions are still stored there. The most dangerous ones have been declared to the UN and are sealed in bunkers.
Although declared, the bunkers contents have yet to be confirmed.
These areas of the compound pose a hazard to civilians and potential blackmarketers.
Numerous bunkers, including eleven cruciform shaped bunkers were exploited. Some of the bunkers were empty. Some of the bunkers contained large quantitiesof unfilled chemical munitions, conventional munitions, one-ton shipping containers, old disabled production equipment (presumed disabled under UNSCOM supervision), and other hazardous industrial chemicals.
