Drone strike a single mission - Pentagonpublished at 16:34 British Summer Time 28 August 2021
More on the overnight drone strike now, and Pentagon spokesman John Kirby says those targeted were affiliated with IS-K, or the Islamic State Khorasan Province group.
"It was a single mission to get these targets," he says.
"They were IS-K planners and facilitators... that's enough of a reason."
IS-K earlier said it had carried out an attack outside Kabul airport on Thursday that may have killed as many as 170 people, including 13 US troops.
"We're going to defend ourselves," Kirby adds.
