The United States carried out a military strike on Sunday in Kabul, news agency Reuters reported quoting two U.S. officials.
The official, speaking on condition of anonymity, said the strike targeted suspected ISIS-K militants.
Witnesses reported an explosion near Kabul airport and television footage showed black smoke rising into the sky. There was no immediate word on casualties.
Two witnesses said the blast appeared to have been caused by a rocket that struck a house in an area to the northern side of the airport, but there was no immediate confirmation.
