Violence between the army and a paramilitary group called the Rapid Support Forces (RSF) continued overnight into its third day.

Nearly 100 people have been killed, a doctors' union said, and one estimate put the number of injured at 1,100.

Both sides claimed to control key sites in the capital Khartoum, where residents sheltered from explosions.

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.

The fighting is between army units loyal to the de facto leader, Gen Abdel Fattah al-Burhan, and the RSF, a notorious paramilitary force commanded by Sudan's deputy leader, Mohamed Hamdan Dagalo, better known as Hemedti.
