Pakistan's military says its warplanes have targeted three militant hideouts in a Taliban stronghold near the Afghan border, killing at least 20 insurgents.

An army statement says Tuesday morning's "precise" air strikes also destroyed two ammunition depots of militants in the Khyber tribal region in the country's northwest.

The identity of the dead was not immediately known and the military gave no further details. Pakistani tribal areas are off limits to journalists.

Pakistan is a key ally of the United States. The latest airstrikes come at a time when the country's security forces are carrying out a major offensive against Pakistani Taliban and foreign militants in the troubled North Waziristan tribal region.
