The US military opened an investigation into the killing of 10 family members in a drone strike targeting a suicide bomber.
Six children, aged between two and 12, were among the reported victims of the same family.
The victims were in a car parked at their home before being hit by a rocket.
A Big Mistake?
The US, he added, had made “a mistake, it was a big mistake”.
US Central Command has said they are investigating reports of the incident, but are unclear how the 10 died.
Ramin Yousufi, a relative of the victims, said: “It’s wrong, it’s a brutal attack, and it’s happened based on wrong information.”
Another relative, Emal Ahmadi, told the BBC that it was his two-year-old daughter who was killed in the strike.
Ahmadi said he and others in the family had applied for evacuation to the US, and had been waiting for a phone call telling them to go to the airport.
Second Attack, One Victim
Last week, at least 69 were killed, several others wounded in the two blasts outside Kabul airport. 12 US soldiers were among the victims.
US President Joe Biden pledged to retaliate against the attack and confirmed ISKP carried out the suicide bombings.
“We will hunt you down and make you pay. I will defend our interests in our people with every measure at my command,” he said.
For his part, NATO Secretary-General Jens Stoltenberg also expressed anger and sorrow.
