Unidentified gunmen shot and killed 20 coal miners in Pakistan's southwestern Balochistan Province early on October 11, police said. The attack occurred at a coal mine in Balochistan's Duki district, local officials told RFE/RL. Police official Humayun Khan told journalists that the attackers also used rocket-propelled grenades. Doctors at a hospital in Duki said they had received 20 bodies and seven injured. No group has claimed responsibility for the attack. Mineral-rich Balochistan has been rocked by a series of militant attacks since the start of the year. Baluch separatist groups, such as the Balochistan Liberation Army (BLA), designated as a global terrorist organization by the United States, are engaged in fighting against the Pakistani government.
