Supporters of Tahir ul-Qadri, a Sufi cleric and leader of Pakistan Awami Tehreek (PAT) party, walk out of the house which was used by police after storming it, during the Revolution March in Islamabad September 1, 2014. Pakistani soldiers and paramilitary forces secured the headquarters of the state television channel PTV in Islamabad on Monday after a crowd of anti-government protesters stormed the building and took the channel off the air. Protesters led by opposition leaders Imran Khan, a hero cricket player turned politician, and ul-Qadri, a firebrand cleric, have been on the streets for weeks trying to bring down the government of Prime Minister Nawaz Sharif.
