CIA drone strike kills al-Qaeda leader Ayman al-Zawahiri in Kabul

A CIA drone strike kills al-Qaeda leader Ayman al-Zawahiri on the balcony of a safe house in Kabul, Afghanistan, 21 years after he helped plan the September 11, 2001 attacks and following Osama bin Laden as al-Qaeda's top figure. Biden announces the operation from the White House, stating "Justice has been delivered." The strike validates Biden's "over the horizon" counterterrorism strategy, the premise that the U.S. could maintain counterterrorism capability in Afghanistan without keeping troops on the ground. Zawahiri had been living in a house owned by a senior Taliban official, raising questions about Taliban commitments under the Doha Agreement.
