MIRANSHAH: Suspected militants fired rockets at a military post in a Pakistani tribal region near the Afghan border, triggering a gunbattle but causing no casualties, an official said on Tuesday. The attack happened late on Monday on the outskirts of Miranshah, the main town in North Waziristan, but “the terrorists fled toward nearby mountains when our soldiers returned fire,” said the official on condition of anonymity. Although the official gave no further details, residents said the exchange of fire continued for two hours. Militants suspected of having ties with remnants of Al-Qaeda and Taliban often launch attacks against security forces. The latest attack came hours after Pakistani forces shot and killed two suspected militants after a grenade attack wounded five soldiers in the nearby town of Mir Ali. The troops were patrolling a bazaar there when one of the two assailants hurled a grenade at them, according to a local government official.
