Pakistan is facing a massive law and order breakdown after thousands of protestors, supporters of Imran Khan, stormed into the national capital, Islamabad.

Pakistani security forces pushed a protester off a 25-foot tall stack of shipping containers as they were accused of opening fire on supporters of Imran Khan at a huge demonstration in Islamabad.

Authorities have reopened roads linking Pakistan’s capital with the rest of the country, ending a four-day lockdown, after using tear gas and firing into the air to disperse supporters of imprisoned former Prime Minister Imran Khan who demanded his release from prison.
