QUETTA Unidentified assailants Tuesday shot dead a woman assistant professor of University of Balochistan in yet another incident of target killing in the provincial capital. Meanwhile, Balochistan Liberation Army (BLA) has claimed responsibility for the attack while Academic Staff Association (ASA) has announced a three-day boycott of classes at the University of Balochistan and three-day mourning at all the varsities across the country over the tragic assassination. Official sources say Nazima Talib (49), Assistant Professor at the Department of Mass, was on her way to Radio Station Quetta in a rickshaw when armed attackers opened fire on her at Sariab Road near Magsi House. As a result, she sustained critical wounds and died on the spot. Police took her body to Civil Hospital for autopsy. The assassins easily escaped from the scene after committing the crime. She had received a bullet in her neck, which resulted in her instant death, hospital sources said. According an eyewitness, the armed masked men fired three gunshots on rickshaw. The driver of rickshaw remained unhurt in the attack. As news of the murder spread in the city, a large number of students and teachers rushed to the hospital to express their grief and sorrow. It is a target killing, however, investigation is underway to ascertain the real motive behind the incident, a senior police official said. It is the first incident of target killing in the province, in which a woman has been targeted. Mansoor (23), son of the slain teacher, told TheNation that her mother had never mentioned receiving a threat from any organisation. Balochistan University Vice-Chancellor, Rasool Bakhsh Raisani, condemned the murder, saying whoever targeted her had committed a heinous crime. The killers have violated our tribal customs by murdering a woman, a guest and a teacher, he added. Nazima Talib belonged to Punjab and was serving in varsity for the last two decades. ASA President Kaleemullah Barech talking to TheNation strongly condemned the targeted killing of his fellow teacher and said ASA would boycott the classes in Balochistan University for three days as protest while mourning would be observed in all the varsities throughout the country. The government has failed to curb the incidents of target killing as prior to this incident two senior teachers were also gunned down in same style, he said, adding that around 100 Punjabi-speaking teachers had submitted applications for their transfer to other provinces and the government should immediately approve their applications. Barech lamented over the incident and said killing a women was against the Baloch and Pakhtun customs and said no government official had bothered to visit the hospital to at least condemn the incident. On the other hand, Chief Minister Nawab Aslam Raisani also condemned the killing of the woman teacher and ordered an investigation into the incident. It is worth recalling that an acting pro-vice chancellor of University of Balochistan and a librarian have fallen prey to target killings like many other teachers in Quetta and other towns of the province. Body of the slain teacher has been flown to her native town for burial while the police have registered a case against unidentified people and started investigation into the incident. Meanwhile, defunct BLA has claimed the responsibility for the murder of Nazima Talib. Meerak Baloch identifying himself as the BLA spokesman said the woman teacher was shot dead in reaction to the killing of Baloch women and children in military operation in Dera Bugti and Kohlu. He said the security forces had also killed Yasmin Baloch in Pasni, sprayed bullets on a womens rally at Tump and recently tortured Shahnaz Bibi to death in Sariab area of Quetta during a search operation. He further said despite BLAs warning of retaliation in same coin, by targeting settler women in case the atrocities against Baloch women were not stopped, the security forces continued their actions, forcing the BLA to take the extreme step of killing a settler professor of university. He also warned of more such attacks if the security forces continued their operation in the province.
