QUETTA-Police arrested over 40 young doctors after shelling and firing in the air after their attempt to make a sit-in before Chief Ministers Secretariat and Governor House to press the government to accept their demands on Tuesday. Seven doctors were reported to have been injured. Police officer Muhammad Ayaz said that the young doctors took out their rally from provincial Sandeman Hospital and started moving towards Chief Ministers Secretariat and Governor House despite police request not to go there. However, when the protesters started to move to Sharey Zarghoon from Enscomb, the police fired few tear gas shells and few bullets in the air to disperse the protesting doctors. As a result seven doctors received injuries who were later shifted to hospital for medical treatment. The police say that although the protesting doctors were arrested, no case so far had been registered against them and they might be released after seeking surety bonds or individual guarantee that they would not violate the law in the future. The young doctors are protesting over the government action of sacking of over 150 of them for observing strike for the last a couple of months in government hospitals in Quetta and in the interior of the province. These doctors had gone on strike not attending the patients in the hospitals to press the government for increasing their salaries. The government after many notices and their failure to resume their duties sacked some 150 doctors and appointed the fresh ones in the same number. Meanwhile, the young doctors have announced to observe a country-wide strike from Wednesday (today) against manhandling of doctors in Quetta and detention of several association members.
