At least six members of a family were killed in a “drone attack” in Khost province, members of the Khost provincial council said Saturday.

According to the provincial council, the six people were killed in a village in Alisher district and the drone targeted a civilian’s home.

Children are also among the victims, the council members claimed.

A spokesman for US forces in Afghanistan confirmed an airstrike in Khost in Terazai district that “targeted three Taliban fighters.” The spokesman added “we are aware of the allegations of civilian casualties” and said they are “working with local authorities to determine the veracity of these claims. “

Meanwhile, former President Hamid Karzai in a tweet condemned the strike.

“The latest US drone attack in Khost, which killed six members of a family, was atrocious and highly condemnable. This is clear and blatant violence against the Afghan people. I once again call on all sides to focus entirely on the peace process,” Karzai tweeted.
