Hundred of protestors of Pakistan Tehreek e Insaf (PTI) and Pakistan Awami Tehreek (PAT) have stormed into the Head Office of Pakistan's state-owned TV channel PTV. On 1st of September at around 11:20 am protesters broke open the main gate of Pakistan Television (PTV) Head Quarters in Islamabad and the station went off air soon.

Since August 14, 2014, tens of thousands of peaceful protesters have been camping out demanding that the Prime Minister Nawaz Sharif should step down.
