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.

There have been reports of mass executions and crimes against humanity 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, as stated by UNHCR's Eujin Byun.

They recounted horrendous stories of atrocities, including rape, while the agency struggles to find shelter and food for the displaced. Notably, every child encountered was suffering from malnutrition.

Currently, over 150,000 people are still trapped in el-Fasher, previously the army's last stronghold in the western region of Darfur.

The RSF has denied widespread allegations of ethnically motivated killings targeting non-Arab populations.

While tensions rise, the RSF has detained a militiaman accused of summary executions, amid the ongoing turmoil of the civil war that erupted in April 2023, resulting in accusations of genocide in Darfur.

As the conflict rages on, the humanitarian crisis in Sudan deepens, marking one of the largest displacements globally, with an estimated 12 million people having fled their homes.
