PESHAWAR (AFP) - A suicide car bomber rammed a paramilitary vehicle on the edge of Peshawar Tuesday, killing five people and wounding more 21, officials said. The suicide attacker rammed his car into the military vehicle. Four civilians were killed and nine people wounded, including four security personnel, local police official Mohsil Ali told AFP. We have received four bodies. All are civilians, Doctor Mohammad Rehan told AFP from the main local government hospital. One FC (paramilitary Frontier Corps) soldier also died, he added. The targeted vehicle belonged to the Frontier Corps, which is responsible for security in the border areas with Afghanistan, another police officer Abdul Ghafoor said. As the vehicle stopped at a police checkpoint the bomber hit his explosive-laden car from behind which exploded with a big bang, Ghafoor said. The injured included six paramilitary soldiers, four police officials and 11 civilians, including several children who were waiting for their school van, he said. Two soldiers were in serious condition, he added. The dead included one school student, Ghafoor said. The military vehicle escaped major damage but four other vehicles behind the explosive laden car were badly damaged, an AFP reporter said. The blast blew up the police barrier and damaged several nearby shops. Bomb disposal squad official Khushal Khan said more than 100 kg of explosives had been packed into the bomb. No one claimed responsibility for the blast, which came as security forces were locked in fierce fighting with Taliban militants in the northwest.
