QUETTA: A roadside bomb exploded, killing three people in insurgency-hit southwestern Baluchistan province on Sunday, police said. Police officer Mohammad Rahim said the bomb was planted on a dirt road in Balgatar area of Kech district and was detonated remotely. Three men, two of whom were brothers, were killed while on their way to a family gathering, and a privately owned car was destroyed, he said. No group immediately claimed responsibility for the blast but suspicion falls on Baluch nationalists turned separatist groups who have been involved in low-level insurgency for over two decades in the gas and mineral-rich province. The groups have been calling for independence from the central government in Islamabad. Kech district and surrounding areas have suffered from insurgency for years.
