Bin Laden (also known as "Osama") is on the Bureau's top ten most wanted list for his involvement in the bombings of U.S. Embassies in Kenya and Tanzania, which killed over 200 people. He is also suspected for several other terrorist plots throughout the world, including the September 11th attacks. An additional $2 million reward is being funded by the Airline Pilots Association and the Air Transport Association.
The reward is actually from the Rewards for Justice Program, a program of the the U.S. State Department, not the FBI. As of right now, Bin Laden is the only one of the Ten Most Wanted Fugitives that whose rewards are not from the FBI. He is also the only terrorist and al-Qaeda member on the list. Bin Laden is described as between 6'4" to 6'6" but only 160 lbs (tall and really skinny). He is left-handed, walks with a cane, and sometimes goes by the alias "The Director".
