American officials estimate that, from 1985 to 1992, 12,500 foreigners were trained in bomb-making, sabotage and urban guerrilla warfare in Afghan camps the CIA helped to set up.
Since the fall of the Soviet puppet government in 1992, another 2,500 are believed to have passed through the camps. They are now run by an assortment of Islamic extremists, including Osama bin Laden, the world’s most wanted terrorist.
