A boy sells newspapers as he walks past a campaign truck and cars of Imran Khan, Chairman of the Pakistan Tehreek-e-Insaf (PTI) political party, during what has been dubbed a "freedom march" in Islamabad August 22, 2014. Khan, who has been leading protesters trying to bring down Prime Minister Nawaz Sharif, said talks with the government were suspended on Thursday, as the continuing impasse raised fears for the nuclear-armed country's stability. Former cricketer Khan and cleric Tahir ul-Qadri, who controls a network of Islamic schools and hospitals, have been leading protests in the capital, Islamabad, since last Friday.
