STORY: Zawahiri, an Egyptian surgeon who had a $25 million bounty on his head, helped coordinate the Sept. 11, 2001, attacks that killed nearly 3,000 people.
U.S. officials, speaking on the condition of anonymity, said the United States carried out a drone strike in the Afghan capital Kabul on Sunday morning at 6:18 a.m. local time.
"Now justice has been delivered, and this terrorist leader is no more," Biden said in remarks from the White House. "We never back down."
