Members of the UN Security Council are warning of possible atrocities and a worsening humanitarian crisis in Sudan as the paramilitary Rapid Support Forces advance towards the city of El-Obeid in Kordofan state.
The council called on the RSF not to launch an attack on the city, which lies in a strategic area linking central and western Sudan.
The warning came days after UN Secretary General António Guterres urged the international community to press Sudan's warring parties to avoid further bloodshed.
