Islamabad: Security forces on Tuesday shot dead a man, whom police claimed was affiliated with the Pakistan Tehreek-e-Insaf party, after he allegedly opened fire on them at a check post on the Mall Road close to the army's General Headquarters in the garrison city of Rawalpindi. "The attacker, Muhammad Hussain, was immediately killed in retaliatory fire," said a statement by Rawalpindi police. The police added that evidence skimmed from the mobile phone of the dead man showed that he was associated with a political party. The "links have emerged from his mobile phone and other belongings," they said. Citing security sources, state-run PTV News said the assailant was a resident of Khyber district and an "active PTI member".
