Fierce clashes have been reported across Sudan as fighting between rival armed factions continues to spread.
Violence between the army and a paramilitary group called the Rapid Support Forces (RSF) continued overnight into its third day.
More than 50 people have been killed, and one estimate puts the number of injured at more than 1,000.
Both sides are claiming they control key sites in the capital, Khartoum, such as the presidential palace.
Earlier on Sunday, they held a temporary ceasefire to allow the wounded to be evacuated, although it was not clear how strictly they stuck to it.
Doctors warned that the situation at hospitals in Khartoum is extremely difficult, and that the fighting was stopping both staff and medical supplies from reaching injured people.
The fighting is part of a vicious power struggle within the country’s military leadership, which has escalated into violence between rival factions.
The two men at its centre disagree over how the country should transition to civilian rule. Sudan has been run by generals since a coup overthrew the long-standing authoritarian president, Omar al-Bashir, in 2019.
