The Sudanese army and rival paramilitary Rapid Support Forces have agreed to a 72-hour new ceasefire brokered by Saudi-US mediators after fighting intensified with deadly air strikes in the capital, Khartoum.

The mediators said “the two sides agreed that during the ceasefire period they would refrain from movements and attacks, the use of warplanes or drones, artillery bombardment, reinforcement of positions, resupply of forces, or refrain from attempting to achieve military gains.”

“They also agreed to allow freedom of movement and the delivery of humanitarian aid throughout Sudan.”

The ceasefire is due to take effect on Sunday from 6 am local time, the mediators said.

The Sudanese Army, led by Abdel Fattah al-Burhan, has been fighting the paramilitary Rapid Support Forces, RSF, led by his former deputy Mohamed Hamdan Daglo, since April 15.

The war has taken a heavier toll in West Darfur with 1,100 people killed in the capital, El Geneina alone, according to the US State Department.

West Darfur Governor Khamis Abdullah Abakar was among those killed after criticizing the paramilitaries in a televised broadcast on Wednesday. The RSF denied all responsibility.

The International Organization for Migration (IOM) estimates that at least 149,000 individuals have fled Darfur into Chad.

They are among the roughly 2.2 million Sudanese uprooted worldwide by the war, which has led more than 528,000 to seek asylum in neighboring countries, according to the International Organization for Migration.
