A bomb blast in Pakistan's southwestern province of Balochistan killed at least four people and injured 15 others on Monday.
The bomb targeted a police vehicle in a busy market in Quetta, the capital of Balochistan, which is home to a separatist insurgency and several Islamist armed groups, reports AFP.
"Initial probe suggests that the explosion was caused by an IED (improvised explosive device) that had been planted on a motorcycle and was detonated using remote control," police official Azfar Mehsar told the news agency.
The Balochistan Liberation Army (BLA), a separatist group, claimed responsibility for the attack.
