Two missiles fired from a US drone struck a militant facility in Afghanistan, leaving 21 insurgents dead including the son of the head of the Pakistani Taliban, Pakistani intelligence officials and local Taliban say.
The officials say the strike on Wednesday targeted a compound frequented by Mullah Fazlullah, the leader of the Pakistani Taliban who is believed to be hiding in Afghanistan.
They say Fazlullah was apparently not there but his son was killed.
The Associated Press reported citing the officials that the strike occurred in Afghanistan's Kunar province, miles away from Pakistani border.
Three Pakistani Taliban commanders also confirmed the strike and militant casualties.
Pakistani officials and the Taliban commanders spoke on condition of anonymity as they weren't authorised to speak to reporters. The US made no comment on the strike.
