Dispute over Khan's medical care reaches country's top courts

Pakistan's government and the party of jailed former Prime Minister Imran Khan are due back at the negotiating table today, ahead of a planned march by supporters on Islamabad on Sunday. The first round of talks ended yesterday, with both sides agreeing to continue discussions. This isn't the first time Imran Khan's party has called supporters on to the streets to demand his release. But now, the dispute over his medical treatment has brought the roles of Pakistan's two highest courts into focus. Hira Mustafa reports for CNA from Islamabad.
