According to the UNHCR, more than 60,000 individuals have escaped the Sudanese city of el-Fasher, which was taken over by the militia RSF over the weekend.
Accounts suggest mass executions and atrocities as militia members stormed the city following an extended blockade marked by food shortages and sustained attacks.
The exodus of those fleeing the conflict towards the community of Tawila, roughly 80km (50 miles) to the west of el-Fasher, had grown in the last several days, according to United Nations refugee agency representative.
They were narrating shocking tales of violence, featuring rape, and the humanitarian group was having trouble to find adequate shelter and supplies for them.
All children was experiencing malnutrition, she commented.
Estimates suggest that in excess of 150,000 people are presently unable to leave in el-Fasher, which had been the army's last stronghold in the western region of Darfur.
The RSF has denied widespread claims that the executions in el-Fasher are ethnically motivated and resemble a pattern of the Arab fighters targeting ethnic minorities.
Nevertheless the RSF has detained one of its members, Abu Lulu, who has been implicated in on-the-spot executions.
The group shared recordings revealing the fighter's detention after verification that he was behind the death of multiple non-combatants in the vicinity of el-Fasher.
Video sharing service has confirmed that it has banned the profile connected to Lulu. Uncertainty exists whether he had managed the account in his identity.
Sudan was thrown into a domestic fighting in April 2023 after a vicious struggle for power erupted between its army and the Rapid Support Forces.
The conflict has caused a starvation emergency and accusations of mass killing in the western Darfur region.
More than 150,000 individuals have lost their lives in the conflict across the country, and about 12 million have left their homes in what the UN has called the biggest global humanitarian disaster.
The capture of el-Fasher solidifies the geographic split in the country, with the RSF now in control of Sudan's west and much of adjacent Kordofan to the south, and the military occupying the capital, Khartoum, central and eastern areas along the coastal region.
The competing factions had been collaborators - taking over together in a seizure of power in 2021 - but disagreed over an foreign-endorsed proposal to move towards civilian rule.
