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.

Mr Khan’s Pakistan Tehreek-e-Insaf (PTI) said a “massacre” unfolded in Pakistan and the armed forces fired live rounds, killing “hundreds of people” and many injured with gunshot wounds. It did not give a number as to how many were killed.

Thousands of people are in the heart of Pakistan’s capital to demand the release of imprisoned former premier Imran Khan.

Bushra Khan, the wife of Pakistan's former Prime Minister Imran Khan, emerged from the shadows this week to lead one of the country's largest protests, mobilizing thousands in support of her jailed husband.

Supporters seeking the release of imprisoned Pakistani former premier Imran Khan on Tuesday broke through a ring of shipping containers locking down the capital Islamabad, battled police, and ignored a government threat to respond with gunfire.

At least one policeman was killed and dozens of people injured in Pakistan as supporters of jailed former Prime Minister Imran Khan clashed with security forces outside the capital Islamabad on Monday,
