Supporters of jailed ex-PM Imran Khan march on Islamabad, protesting against the Shehbaz Sharif government and demanding Khan’s release. The government vows to suppress the protests, while the US urges restraint from both sides. Controversy surrounds Khan’s wife, Bushra Bibi, over statements allegedly critical of Saudi Arabia, which Khan denies.
