Gunmen on Tuesday shot dead a woman university professor in Quetta, where targeted killings blamed on tribal insurgents, sectarian groups and militants are increasing, police said. Nazima Talib, 48, had just stepped into a rickshaw at the gate of Balochistan University in Quetta city when gunmen riding a motorbike sprayed her with bullets, senior police officer Tariq Manzoor said. She received multiple bullet wounds and died before she could be taken to hospital, Manzoor told a foreign news agency. It was a targeted killing, he said. Talib came from Pakistan's central province of Punjab that regional insurgents in Balochistan accuse of siphoning off their resources and denying them independence, police said.
