A roadside bomb near a police checkpoint in Pakistan's southwest has left one person dead and at least 10 injured, the Associated Press reported.
Senior police official Wazir Khan Nasir told media outlets that no group immediately claimed responsibility for the bomb. The AP reported that the area has been home to a "low-level insurgency" carried out by Baluch nationalist groups, as well as militants affiliated with al Qaeda.
The bomb, which was attached to a motorcycle, was detonated at a police checkpoint in the city of Quetta, the provincial capital of Baluchistan, on Monday.
PressTV reported Pakistani police forces were the target of the roadside-planted bomb, although the AP reported that most of the victims were civilians.
Three police officers were taken to a local hospital immediately after the blast.
The death toll is expected to rise as most of the injured are said to be in critical condition, the television network reported.
ABC News reported the bomb was detonated through a remote-controlled device.
Senior police official Wazir Khan Nasir told media outlets that no group immediately claimed responsibility for the bomb. But the province has long been the scene of a low-level insurgency involving Baluch nationalist groups.
The bombing follows last Wednesday's attack when a gunman shot dead two people, including a Shia Muslim, in Quetta.
Almost 400 Shias have been killed in targeted attacks in the country this year.
