#11 Muhsin Fadhli
Fadhli, who fought for the Taliban as a teenager in Afghanistan, had advanced notice of the Sept. 11 attacks. Years later, U.S. intelligence analysts had fears that his faction was progressing in its ability to attack airliners and other Western targets.
The head of a shadowy cell of veteran al-Qaeda operatives known as the Khorasan Group, he was killed while traveling in his vehicle near the Turkish border in the Syrian town of Sarmada. He was identified as the authority of al-Qaeda’s operations in Iran before relocating to Syria.
