Pak: US drone strike kills 4 militants in North Waziristan

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 last night and targeted a house in Qutab Khel village, five kilometres 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.
