Quetta- Two persons, including a woman were injured today when militants blew up the shrine of a Sufi saint in Balochistan's Mastung district, police said. The shrine located in the main commercial area of Mastung was completely destroyed due to the explosion. Police official Nazeer Ahmed said that militants had planted explosives inside the shrine of Sheikh Taqi Baba. "Explosive materials went off with a loud bang this morning," he said. The blast rocked the entire Mastung city, causing panic among the people. Police and other law enforcement personnel reached the area as an investigation into the incident went under way. There was no immediate claim of responsibility for the attack. Militants in recent days have intensified attacks against security forces and national installations in Balochistan, a province plagued by an insurgency and growing sectarian killings for more than a decade.
