Ahmad Shah Massoud, commander of the Northern Alliance, an anti-Taliban coalition, is assassinated by al-Qaeda operatives. The killing of Massoud, a master of guerilla warfare known as the Lion of the Panjshir, deals a serious blow to the anti-Taliban resistance. Terrorism experts believe his assassination assured Osama bin Laden protection by the Taliban after the 9/11 attacks. Expert Peter Bergen later calls Massoud’s assassination “the curtain raiser for the attacks on New York City and Washington, DC.”
