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.

Pakistan has put the capital Islamabad under lockdown as thousands of supporters of jailed former prime minister Imran Khan marched towards the city to demand his release, in the latest threat to the legitimacy of the military-backed government.

Internet and mobile services will continue to operate as usual in the rest of the country,” the posts said. A spokesperson for the Interior Ministry was not immediately available for comment. Khan has been in prison for more than a year and has over 150 criminal cases against him.
