The Islamic fundamentalist leader Osama bin Laden (born 1957), a harsh critic of the United States and its policies, is widely believed to have orchestrated the 1998 bombings of two U.S. embassies in East Africa, as well as the October 2000 attack on the USS Cole in the Yemeni port of Aden. But it is his role as the apparent mastermind of the September 11, 2001, attacks on the World Trade Center and the Pentagon that have made bin Laden one of the most infamous and sought-after figures in recent history.

The 6-foot-5, lanky, bearded leader--soft-spoken and effeminate, even when he rails against America--is a man of tremendous wealth, and makes an unlikely spokesman for the poor and oppressed people of Islam whom he claims to represent. Nevertheless, his call for a jihad, or holy war, against the United States and Israel, has been heeded by like-minded fundamentalist Muslims.
