In Sudan, the U.N.'s migration agency says more than 36,000 people have fled El Fasher since the city was seized by the paramilitary Rapid Support Forces last week, after 18 months under siege. Displaced families were forced to walk to the neighboring town of Tawila, which is already sheltering more than 650,000 people forced out of their homes. Survivors described streets littered with corpses and families separated by violence, with those displaced forced to trek for days without food or water. This comes as famine grips El Fasher and the town of Kadugli, according to a report by the Integrated Food Security Phase Classification, the world's leading authority on food crises. Famine is also threatening to spread to 20 other areas in the Darfur region and central Sudan’s Kordofan region, as fighting between the Sudanese government and the RSF rages on. Meanwhile, the RSF has vowed to take over the city of el-Obeid in central Sudan, currently under control by the Sudanese army.
