AKIPRESS.COM - The United States killed al Qaeda leader Ayman al-Zawahiri in a drone strike, President Joe Biden said Monday in a speech from the White House, CNN reported.

"I authorized a precision strike that would remove him from the battlefield, once and for all," Biden said.

Zawahiri, who just turned 71 years old, had remained a visible international symbol of the group, 11 years after the US killed Osama bin Laden. At one point, he acted as bin Laden's personal physician.

Zawahiri was sheltering in downtown Kabul to reunite with his family, Biden said, and was killed in what a senior administration official described as "a precise tailored airstrike" using two Hellfire missiles. The drone strike was conducted at 9:48 p.m. ET on Saturday was authorized by Biden following weeks of meetings with his Cabinet and key advisers, the official said on Monday, adding that no American personnel were on the ground in Kabul at the time of the strike.
