Usāmah bin Muhammad bin `Awad bin Lādin (born March 10, 1957) (Arabic: أسامة بن محمد بن عود بن
لادن), commonly known as Osama bin Laden (أسامة بن
لادن), is the figurehead of al-Qaeda, an Islamist movement that has been involved in attacks against civilians and military targets around the world. He is believed to have
inspired the September 11, 2001 attacks on New York and Washington (9/11), which killed at least 2,752 people.
His immensely wealthy family publicly disowned him in 1994, shortly before the Saudi Arabian government revoked his citizenship. He attended his son's wedding in January 2001, but since 9/11 is believed only to have had contact with his mother on one
occasion. (See Osama and the September 11 Terrorist Attacks below.)
One of Bin Laden's main goals was to force the removal of U.S. military bases in Saudi Arabia, where two of Islam's holiest places are located. The U.S. has announced that it will close its bases, although it is unclear whether Bin Laden's
activities were a factor in this decision.
Bin Laden is probably the "most wanted" man in the world with a reward for information leading to his capture of US$50
million. His current whereabouts are unknown, although he is widely believed to be hiding along the Afghanistan-Pakistan border or in the semi-autonomous Pakistani tribal area of the Toba Kakar Mountains near Waziristan.
