PESHAWAR (Agencies) - At least four people including a child were killed Monday in a car bomb blast targeting an anti-Taliban vigilante leader on the outskirts of Peshawar, police said. The bombing outside the compound of local anti-Taliban vigilante commander Altaf Khan in Matni suburb of Peshawar also wounded seven others and damaged a boundary wall and shops in the street, they said. At least four people were killed and seven others were wounded, a police official said, confirming the blast came from a car bomb. A nine-year-old child is also among the dead, he said. Peshawars bomb disposal chief Hukam Khan said up to 50 kilograms of explosives were packed in the car and detonated remotely. Insurgents have previously targeted members of anti-militant tribal militias which are known as Lashkars. Nearly 4,500 people have been killed across Pakistan in attacks blamed on Taliban and other extremist networks based in the nearby tribal belt since government troops stormed Lal Masjid in Islamabad in 2007.
