KHAR (AFP) - Suspected Taliban fighters blew up two girls' schools on Wednesday while eight militants were killed in clashes with the military in northwest Pakistan, an official said. The two primary schools were detonated in the Nawagai and Salarzai areas of Bajaur, where the military has waged a massive offensive designed to clear the area of extremists. "There was no loss of life in the twin attacks, as girls schools are closed in the region," said local government official Farooq Khan. Militants have destroyed 30 schools, most of them for girls, in different areas of Bajaur since August 2008, Khan said. On Wednesday, Khan said troops, backed by helicopter gunships, killed eight militants in battles with extremists. "Troops targeted rebel hideouts in an operation backed by fighter jets, helicopter gunships and artillery, killing eight militants and wounding five others," he told AFP. Troops carried out the raid in response to rebel attacks on its forces in Khar, the main town of Bajaur, and elsewhere overnight.
