Saudi Arabia and the United States called on Sunday for the extension of a ceasefire deal that has brought some let-up in a six-week war between military factions, but said both sides had impeded aid efforts and were posturing for further escalation.
Clashes could be heard overnight and on Sunday in the capital Khartoum, residents said, while human rights monitors reported deadly fighting in El Fashir, one of the principal cities in the western region of Darfur.
