Islamabad, Sept 2 (ANI): Pakistan Prime Minister Nawaz Sharif is due to address joint session of Parliament on Tuesday in which the ongoing political crisis and the violent protests will be discussed. Pakistan is preparing to launch a selective crackdown against anti-government protesters trying to bring down the government of Nawaz Sharif, the defence minister said, warning demonstrators against storming government buildings. Dashing chances of a peace deal between the government and protest leaders Imran Khan and Tahir ul-Qadri, anti-government protesters stormed the state television building in the heart of the heavily guarded capital earlier on Monday. Protesters have also tried to march on Sharif's residence.
