Six months of war have plunged Sudan into one of the worst humanitarian nightmares in recent history, the UN Emergency Relief Coordinator said on Sunday, calling on the parties to the conflict to uphold their obligations under international humanitarian law.

Up to 9,000 people have been reportedly killed, more than 5.6 million driven from their homes and 25 million people need aid, because of the conflict that erupted in mid-April between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) and other armed groups.
