Biden says US killed al-Qaida leader al-Zawahiri in drone strike

WASHINGTON -- US President Joe Biden announced Monday evening that al-Qaida leader Ayman al-Zawahiri had been killed in a drone strike in Kabul, Afghanistan.

"I authorized a precision strike that would remove him from the battlefield," Biden said in live remarks from the Blue Room Balcony at the White House. "There were no civilian casualties."

Al-Zawahiri became head of al-Qaida in 2011 after its longtime leader, Osama bin Laden, was shot and killed by US forces in Abbottabad, Pakistan during a raid.

Biden's announcement came nearly a year after the US military completed a withdrawal from Afghanistan that it invaded in response to the Sept. 11, 2001, terror attacks carried out by al-Qaida operatives against targets on American soil, which killed nearly 3,000 people.
