During a press briefing Friday, Pentagon press secretary John Kirby revealed that the U.S.-led evacuation of Afghanistan still faces “specific, credible threats.”

“We still believe there are credible threats. In fact, I would say specific threats and we want to make sure we’re prepared for those…We certainly are prepared and would expect future attempts, absolutely, but I won’t get into the specifics of what those are,” he remarked.

Ninety-two people, including 13 U.S. soldiers and 79 Afghan civilians, were killed after a suicide bomber detonated outside the airport’s Abbey gate.
