Foreign Office Minister Alistair Burt said he was “appalled” at the killings and also at an attack on a checkpoint in the province which killed 10 Afghan soldiers.
“I am appalled at the cruel killing of 17 people at a party…. The facts are still being established but early indications are that the Taliban were responsible,” he said in a statement.
“We condemn acts of extreme violence like this in the strongest terms.”
The Taliban were responsible for beheading the civilians, including two women, who were holding a party with music in a southern Afghanistan village, officials said.
