There are reports of heavy fighting and shelling in the city of El Fasher in Sudan’s Darfur region.

Since mid-April the city has been besieged by the paramilitary Rapid Support Forces (RSF). Fighting with the Sudanese army escalated on Friday and since then medical workers say more than 50 people have been killed and around 400 wounded.

The UN said the fundamental laws of war and international humanitarian law are being violated every day during the fight for control of El Fasher, maintaining appeals for the protection of civilians are being ignored.

The city is a refuge for hundreds of thousands of civilians displaced by fighting elsewhere.
