Pakistan's capital, Islamabad, is under lockdown for a second day as thousands of protesters demanding the release of former prime minister Imran Khan from jail converge on the city. His supporters are also calling for the overturning of election results they say were rigged - a claim disputed by the government.

Hundreds of Imran Khan's supporters marched towards Islamabad, demanding his release. Authorities imposed a security lockdown, leading to clashes. Khan's wife vowed to continue the protest until his release.

Protesters demanding the release of Pakistan’s jailed former premier Imran Khan reached the edge of the nation’s capital, authorities said late Monday night, overcoming efforts by Prime Minister Shehbaz Sharif ‘s government to stifle the nationwide protests.
