Jailed former premier Imran Khan's Pakistan Tehreek-e-Insaf has distanced itself from a party leader's invitation to External Affairs Minister S Jaishankar to join its protest, asserting that no foreign country has a role in its political struggle.

Imran Khan's party leaders have been staging protests, claiming that the Pakistan government should adhere to the constitution.

Pakistani authorities have placed shipping containers on key roads and highways leading to the capital and suspended cellphone service in Islamabad in an attempt to prevent supporters of imprisoned former Prime Minister Imran Khan from holding a rally seeking his release.
