The semi-autonomous tribal areas on the Afghan border have for years been a hideout for militants of all stripes, including Al Qaeda and the Pakistani Taliban as well as foreign fighters such as Uzbeks and Uighurs.

Pakistan began a long-awaited push to clear insurgent bases from North Waziristan last June after a bloody Taliban attack on Karachi airport finally sank faltering peace talks.
