A US drone strike targeted a house in Pakistan’s restive North Waziristan tribal region killing at least four suspected militants.
Local officials said the drone attack took place late on Wednesday night and targeted a house in Qutab Khel village, five km from Miranshah, the main town of North Waziristan.
The area is a stronghold for Taliban and al—Qaeda—linked militants.
The identities of those killed in the strike were not immediately known but officials suspect that they were of Afghan origin.
Pakistani government criticises drone strikes as a violation of its sovereignty and counterproductive to anti-terror efforts.
NATO supply routes continue to remain blocked in Khyber Pakhtunkhwa province due to protests over strikes from the CIA-operated spy planes.
