Al Qaeda May Have "Radiological" Weapons
Bill Gertz reports in the Washington Times that al Qaeda may have created radiological weapons, which are primarily designed to deliver large amounts of radiation as opposed to a nuclear blast. Such weapons would attempt to maximize death in a relatively confined area.
The article also refers to possibility that al Qaeda may have built simple chemical weapons that require limited technological expertise. These weapons would contain chemicals like chlorene and phosgene as their payloads.
