FAIR: Forgotten Coverage of Afghan ‘Freedom Fighters’ But the U.S. government and the American press have not always opposed Afghan extremists.

During the 1980s, Bin Laden’s activities in Afghanistan closely paralleled those of the CIA. Bin Laden held accounts in the Bank for Credit and Commerce International (BCCI), the bank the CIA used to finance its own covert actions.

In 1989, the U.S. shipped high-powered sniper rifles to a Mujahiddin faction that included bin Laden, according to a former bin Laden aide.
