US finds no evidence of nuclear, chemical, biological weapons

US experts on the ground in Afghanistan have found no evidence that either Osama bin Laden or the Taliban regime tried to develop nuclear, chemical or biological weapons, according to the commander in charge of the so-called "war on terrorism".

General Tommy Franks said yesterday that his troops have searched more than 40 sites where they suspected such weapons may have been developed, but found no evidence to support their suspicions.
