Reports say that gun battles raged for hours in the Bara area, close to the city of Peshawar on October 17.

At least 14 militants were killed during the clashes, officials say.

The area is home to a number of different militant groups who have been at war with each other and with the Pakistani forces.

In August dozens of people were killed in a suspected suicide attack at a mosque in Khyber.

Khyber has also been targeted by US drones this year - one of the few times such attacks have taken place outside the militants' main sanctuary of Waziristan.
