Militants armed with guns and rockets on Monday blew up a fuel tanker in northwest Pakistan carrying supplies for NATO troops across the border in Afghanistan, officials said. Two people, a driver and his helper, were wounded after about 10 militants ambushed the tanker outside Peshawar, the head of the northwestern city's administration, Sahibzada Anees, told AFP. "About 10 armed people fired at a tanker carrying petrol for NATO forces and later lobbed a rocket at the vehicle, which set alight some 78,000 litres (17,000 gallons) of fuel," Anees said. Nobody claimed responsibility for the attack, he said, but Taliban and members of local militant group Lashkar-e-Islam (Army of Islam) have regularly attacked NATO supply vehicles on the main route through northwest Pakistan.
