Two soldiers and 16 militants were killed in clashes in the Tirah Valley area of the Khyber tribal region in the northwest, the military said in a statement. Another three soldiers were wounded in the remote mountainous district near the Afghan border.
The army launched an offensive last month into the valley targeting the Pakistani Taliban and an allied group, Lashkar-e-Islam. The military statement said the latest fighting forced the militants to flee from two of their hideouts, leaving behind a huge cache of arms and ammunition.
The tribal region is home to both Pakistani and Afghan militant groups, including al-Qaeda-linked organisations with significant numbers of foreign fighters. The military carries out raids against the insurgents, inflicting losses but not preventing them from striking back with roadside bombs and ambushes.
Also today, two members of the paramilitary Frontier Corps were killed in clashes in the Bolan district of the southwestern province of Baluchistan, said government official Waheed Shah. He said the fight also killed 13 "criminals" suspected in kidnappings and robberies.
He said candidate Sardar Sarfraz Domeki's other guards fired back, killing one of the attackers and wounding the other. He said the police were questioning the wounded attacker.
