Air strikes have intensified in Sudan’s capital, Khartoum, despite a truce aimed at allowing civilians to flee.
The army said it was attacking the city to flush out its paramilitary rivals, the Rapid Response Forces (RSF).
The latest truce was due to end at midnight on Sunday. The RSF said it had been extended for another three days.
Millions remain trapped in the capital, where food is running short. The first major aid flight, laden with medical supplies, has arrived in the country.
The International Committee of the Red Cross (ICRC) says a plane landed at Port Sudan with eight tonnes of relief supplies, including health kits for hospitals.
“With hostilities still ongoing, ICRC teams will need guarantees of safe passage from the parties to the conflict to deliver this material to medical facilities in locations with active fighting, such as Khartoum,” a statement said.
More than 70% of health facilities in the capital have been forced to close as a result of the fighting that erupted on 15 April.
