The bomb was planted in a car parked on a highway in Saryab, on the outskirts of Quetta, the capital of impoverished Baluchistan province, which suffers from a separatist insurgency.

"The bomb was planted in a car. One person was killed and six were injured. All of them were civilians," Farid Breach, a senior police official, told AFP.
