Residents of Islamabad are tiring of regular demonstrations demanding the release of the former prime minister Imran Khan, with the marches leading to clashes with security forces.

Thousands of supporters of Pakistan’s jailed former Prime Minister Imran Khan broke through barricades around the capital Tuesday and marched into Islamabad, clashing with security forces and demanding his release.

At least six people have died in protest-related violence as supporters seeking Imran Khan’s release from prison broke through barriers meant to lock down Islamabad.

The crackdown brought a swift end to the protests that have gripped Islamabad, Pakistan’s capital, this week ever since thousands of people gathered in the city to demand the release of Imran Khan, the former prime minister. Mr. Khan has been in prison since last August on charges that his party claims are politically motivated.

Pakistani authorities arrested nearly 1,000 supporters of jailed former prime minister Imran Khan who stormed the capital this week to demand his release, the city's police chief said on Wednesday.

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