The US Central Command said on Friday that US forces conducted a drone strike against a member of the militant group ISIS-K believed to be involved in planning terrorist attacks.
It also said initial indications are that the strike in Nangarhar Province, eastern Afghanistan, killed the target, and there were no known civilian casualties.
The US strike is seen as retaliation against an apparent suicide bombing near Kabul's airport on Thursday, in which many civilians and 13 US service members were killed.
The bombing is believed to have been conducted by members of ISIS-K, a regional affiliate of Islamic State militants.
US President Joe Biden said at a news conference on Thursday, "We will not forgive. We will not forget. We will hunt you down and make you pay."
The Central Command did not reveal details of Friday's operation, including how the targeted ISIS-K member was involved in terrorism.
