US operation killed al-Qaida leader al-Zawahri, Biden addresses nation

A U.S. drone strike in Afghanistan this weekend killed Ayman al-Zawahri, who took over as al-Qaida leader after Osama bin Laden’s death in a U.S. raid. President Joe Biden was set to announce the killing Monday, delivering a significant counterterrorism win just 11 months after American troops left the country after a two-decade war.
