At least four insurgents were killed in a US drones strike in Pakistan's restive tribal region near the Afghan border on Friday, security officials said.
The attack took place in Gurbuz town, 65 kilometres southwest of Miranshah, the main town in North Waziristan tribal district, a security official told AFP.
"The drones fired two missiles on a house believed to be a militant centre. Four militants were killed and two injured," he said.
It comes as another official said eight missiles hit the house and the bodies were burnt beyond recognition.
"We have no information about the identity of those killed in the missile strike," the official said.
A security official in the northwestern Pakistani city of Peshawar confirmed the toll.
Gurbuz lies at Pakistan's border with Afghanistan in a remote mountainous area which is currently facing severe winter cold, he said, adding that a number of militant groups have hideouts in the area.
