Bin Laden is on the American Federal Bureau of Investigation's list of FBI Ten Most Wanted Fugitives due to several 1998 US embassy bombings.
Since 2001, Osama bin Laden and his organization have been major targets of the U.S. War on Terror. Bin Laden and fellow al-Qaeda leaders are believed to be hiding near the border of Afghanistan and Pakistan's Federally Administered Tribal Areas.
