The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) warned on Monday of a sharp deterioration in the situation in El Fasher, the capital of Sudan’s North Darfur State. This warning comes amid reports that the Rapid Support Forces (RSF) captured the Sudanese army headquarters in the city on Sunday. In light of the situation, UN relief chief Tom Fletcher has called for an immediate ceasefire in El Fasher, across Darfur, and throughout Sudan.
