Pakistani officials say air force jets have bombed militant hideouts in the country's volatile northwest.

A Pakistani military official and two intelligence officers said Thursday that 15 suspected militants were believed to have been killed in the air strikes.

All the officials spoke on condition of anonymity because they were not authorized to speak to the media.

The air strikes hit villages in the North Waziristan tribal region, a hotbed of militant activity that borders Afghanistan to the west.

The airstrikes come as government efforts to negotiate a peace deal with the Pakistani Taliban militants who operate out of the region have stalled.

Prime Minister Nawaz Sharif has favoured peace talks over military action to end the bloodshed in the northwest.
