LAHORE-Federal Minister for Railways Saad Rafique today lashed out at MQM head Altaf Hussain, calling him an ungrateful person. Speaking to journalists outside the Parliament House, Rafique said that Hussain had set an unparallel example of betrayal. His remarks came after Hussain announced a day of mourning in Karachi against the brutal crackdown in Lahore in which eight people, including two women, were killed. Reacting to Hussain’s call, he said that Tahir-ul-Qadri was an imposter, who was only creating anarchy. “The nation truly remembers the tactics of Tahir ul Qadri,” he added. The PML-N leader said that judicial commission would launch an inquiry into the violence.
