Protests and riots erupted across southwestern Pakistan on Thursday, leaving one policeman dead, after the discovery of the mutilated bodies of three missing political dissidents, AP reported. The trouble flared in Baluchistan, an impoverished region bordering Afghanistan and Iran. Scores of protesters took to the streets of towns and cities across the province on Thursday morning after the three bodies were brought to a hospital in the town of Turbat. In Quetta, the provincial capital, television footage showed police firing warning shots and swinging batons to disperse demonstrators who torched a bus and a car and blocked several roads with rocks and burning tires. Further south, protesters fired shots toward police in the town of Khuzdar, fatally wounding one officer, police official Ghulam Ali Lashari said.
