The US carried out a defensive airstrike in Kabul Sunday, targeting a suspected ISIS-K suicide bomber who posed an "imminent" threat to the airport, US Central Command said.
Among those killed were nine members of one family -- including six children -- a relative of the dead told a local journalist working with CNN.
One witness said it was 5 p.m. when he heard the noise of a rocket coming.
"I was scared and ducked by the side of the road." The man "waited to see where it will hit and then there was a loud bang."
After the rocket hit, "all the neighbors tried to help and brought water to put out the fire" he said.
He said they included "the father of the family and another young boy and there were four underage children. They were dead. They were in pieces. There were two wounded.
Those who had died "were in a bad state. You could not look at them. It was really horrible," he added.
One neighbor also said he lost his friend in the airstrike.
"The father and children were sitting in the car to go out somewhere," he said adding that "at this point the rocket hit.
"Now there is nothing left in their house. There were 10 or 20 of them who have all been killed. Not much left of their house and nothing can be recognised, they are in pieces."
And another witness said the noise of the rocket was "horrific."
"The family had just driven the car inside the house. All the men folks were in the car," the witness said adding that he and other witnesses "removed six dead bodies."
"These were normal people, they had civilian jobs," he said "The people were not affiliated to anyone," he added.
