KARACHI - Tension gripped the Clifton Town after firing incident when Istikham-e-Pakistan rally by Sunni Tehreek (ST) was being carried out on Thursday on the occasion of Independence Day. The disturbance happened after the firing sound heard when the rally had arrived at Punjab Chowrangi in the jurisdiction of Frere police station, Clifton Town. Tariq Mughal, spokesman for ST claimed that the personnel from the rangers had started firing on the participants of the rally and then police followed the same. The motive behind the incident is yet to be ascertained, he said. He said that after the incident, the rally was moved towards Abdullah Shah Ghazi shrine where the numbers of participants protested. Dozens of ST workers were taken to custody but most of them were released while some others were still in detention.  To a question, he said, "To get release our men from the police station is our first priority, then we will see what to do." There were the reports that some three workers of the ST sustained bullet wounds. Mughal, however, told that it is being checked. On the contrary, DSP Javed Bhatti informed that it was still unclear who fired. "I myself heard some 15 to 20 fires. There is no report of any injury. I think the ST workers themselves resorted aerial firing and put allegations on rangers and police," he maintained. However, the situation is much under control. No one was taken into custody, Bhatti mentioned.
