“By hosting and sheltering the leader of al Qa’ida in Kabul, the Taliban grossly violated the Doha agreement and repeated assurances to the world that they would not allow Afghan territory to be used by terrorists to threaten the security of other countries,” Secretary of State Antony Blinken said in a statement shortly after Biden announced the operation from the White House.

Officials said they believed senior Taliban officials were aware of Zawahiri’s presence in the villa in Kabul’s Shirpur neighborhood and attempted to conceal the attack after the fact.

The Taliban responded to the incident with indignation, calling the drone strike “a violation of international norms” and saying it was the United States who had violated the Doha deal.

A day after Biden heralded Zawahiri’s death, officials said they were reviewing how the Taliban’s willingness to host him would affect issues including U.S. assistance to Afghanistan, the release of billions of dollars in Afghan government reserves held in the United States, and the potential for steps toward normalizing ties with the Taliban.
