An army medic checks the injury of a supporter of Tahir ul-Qadri, a Sufi cleric and leader of Pakistan Awami Tehreek (PAT) party, near a line of soldiers from the Pakistan Rangers blocking a road leading to Prime Minister Nawaz Sharif's house, 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 Sharif.
