A civilian was killed and 12 others including three children injured when a car bomb targeted a paramilitary convoy Tuesday in the southwestern Pakistani city of Quetta, officials said. The explosives-packed car went off after vehicles of the paramilitary Frontier Corps (FC) passed, FC spokesman Murtaza Baig told AFP. "The militants targeted two vehicles of FC but the remote-control device exploded after our convoy had passed the parked car," he said. Police and security forces are frequently attacked in the insurgency-plagued Baluchistan province, of which Quetta is the capital. Senior police official Wazir Khan Nasir told AFP: "The victims of the blast were all civilians who were passing from the area. The toll includes one man killed and 12 others wounded including two women and three children." There was no claim of responsibility for the attack but the province, which borders Iran and Afghanistan, suffers from Taliban and local rebel attacks. It is also a flashpoint for sectarian violence involving Sunni and Shiite Muslims that has left thousands of people dead since the late 1980s. Baluch rebels rose up in 2004, demanding political autonomy and a greater share of profits from the oil, gas and mineral resources in the region, one of the most deprived in Pakistan.
