Former Pakistani Prime Minister Imran Khan has been transferred to a jail near capital Islamabad after a court extended his custody by two more weeks in a state secrets case related to his 2022 removal.

Khan, 70, was moved to Adiala Jail in Rawalpindi city on Tuesday night after having spent more than three weeks in Attock Jail some 100km (62 miles) away where he was sent following his conviction in a corruption case last month.
