He was on the list for more than 10 years, originally wanted for allegedly orchestrating the bombings of U.S. embassies in Kenya and Tanzania. Though the official FBI poster listed his occupation as "unknown," the Saudi Arabianborn leader of al-Qaeda was widely known as the most dangerous terrorist on the planet. But on May 1, 2011, after years of evading capture, bin Laden was killed by U.S. special operations forces inside a heavily fortified compound in Abbottabad, Pakistan, just north of the capital of Islamabad.
While the FBI does not list the 9/11 attacks among bin Laden's crimes, he claimed responsibility for them and often praised the hijackers for completing their mission. Bin Laden's No. 2, Ayman al-Zawahiri, remains on the FBI's most-wanted list. Another international terrorist who once found his way onto the list is Ramzi Yousef, the mastermind behind the 1993 bombing of the World Trade Center. He was caught in 1995 and is serving a life sentence.
