Suspected Taliban militants on Wednesday attacked and destroyed a tanker supplying fuel to NATO troops in neighbouring Afghanistan, police said. A group of 10 armed men ambushed the tanker en route to Afghanistan on the ring road outside the northwestern city of Peshawar and opened fire with Kalashnikovs, wounding both the driver and his assistant. "They ordered the driver and the assistant to get down and fired rockets at the tanker, which triggered a massive fire," senior police official Mohammad Alam Shinwari told AFP. He said the militants were travelling in three cars. Another senior police official, Mohammad Karim Khan, confirmed the incident and said militants fled after the attack.
