António Guterres calls for the violence to end but there appears little appetite for ceasefire proposed by US

The UN secretary general, António Guterres has said the war in Sudan is spiralling out of control as he called for a halt to the fighting and an end to the violence.

The Rapid Support Forces (RSF), which are reportedly backed by the United Arab Emirates, seized El Fasher in Darfur last week after a near 18-month siege. Some of its soldiers have posted videos of civilians being shot, including in the town’s maternity hospital.

The two-year civil war between the Sudanese armed forces (SAF) and the RSF has created what the UN has described as one of the worst humanitarian crises of the 21st century. More than 150,000 people have been killed and more than 14 million displaced from their homes.

Prosecutors at the international criminal court said on Monday that they were collecting evidence of alleged mass killings, rape and other crimes in El Fasher.
