A pamphlet published on the CIA's Web site says al Qaeda documents captured in Afghanistan indicate that the network possesses crude procedures for producing VX nerve agent, sarin and mustard gas. In light of this information, the mainstream media recently have focused on the possibility that al Qaeda will use chemical and/or biological weapons (CBWs) against the United States and U.S. interests abroad. The American public has been besieged with warnings about al Qaeda and its CBW program since shortly after the United States launched a 1998 cruise missile attack against Sudan's Shifa pharmaceutical factory, which Washington said was a terrorist-related facility. STRATFOR also has written about the danger posed by terrorists using chemical or biological weapons on more than one occasion.
