The bomber targeted Frontier Constabulary guards in the Mian Ghundi neighborhood of the city -- close to the Afghanistan border -- where Hazara Shiite merchants were trading vegetables. Azhar Akram, a deputy inspector general of police, told AFP that 20 people were injured in the blast, including civilians. A spokesperson for the police's Counter-Terrorism Department confirmed the toll. Shiite Muslims have been frequently targeted in restive Balochistan by radical Sunni Islamist groups, who consider them a heretical sect. Frontier guards have also been targeted by Baloch insurgents, who have been waging a simmering insurgency for greater autonomy. .
