More than 60,000 people have fled the Sudanese city of el-Fasher, which was captured by the paramilitary Rapid Support Forces (RSF) over the weekend, according to the UN refugee agency. Reports of mass executions and crimes against humanity have emerged as the RSF fighters stormed the city after an 18-month siege marked by starvation and heavy bombardment. The flow of those fleeing the violence towards the town of Tawila, about 80km (50 miles) west of el-Fasher, has increased in the past few days, with the UNHCR facing difficulties in providing sufficient shelter and food. To make things worse, many fleeing survivors share stories of atrocities, including rape and extreme malnutrition among children. Despite the turmoil, the RSF has denied claims of ethnic motivations underlying the violence and killings. Over 150,000 people remain trapped in el-Fasher, struggling for survival in the wake of the RSF's control, which further emphasizes the geographic split in Sudan's ongoing civil war.
