( CNN ) -- Gunmen killed seven people Wednesday in Pakistan 's southwestern Balochistan province , and two more died in a bomb blast in Karachi , police said . The Karachi explosion resulted from a bomb planted near an illegal gambling and drug center , according to police official Muhammad Aslam . It was not immediately clear who placed the bomb . In Balochistan , four people died in Loop Sherani when gunmen on two motorcycles sprayed a vehicle with what police official Abdul Jabbar Baloch called `` indiscriminate firing . '' The shooting appeared to be a targeted killing , he said . In the other Balochistan incident , gunmen killed three people in Quetta , the provincial capital . Deputy Inspector General Wazir Khan Nasar said gunmen had earlier kidnapped the victims , who were later shot repeatedly in the head from close range . Balochistan , Pakistan 's largest province , is routinely racked with violence . This month , 97 people have died in bombings in the province , leading to protests among Shiites who complain that the government has done too little to protect them . In addition to sectarian attacks on Shiites , unrest in the province is believed to be fomented by several insurgent groups , including the separatist Balochistan Liberation Army and the Pakistani Taliban . CNN 's Shaan Khan contributed to this report .
