Sudan's paramilitary forces killed hundreds of people including patients in a hospital after they seized el-Fasher city in the western Darfur region over the weekend, according to the U.N., displaced residents and aid workers, who described harrowing details of atrocities.

The World Health Organization, said in a statement the 460 patients and companions were reportedly killed at Saudi Maternity Hospital in el-Fasher, the provincial capital of North Darfur.

"We condemn the continued violations of international humanitarian law and the violation and abuses of human rights taking place in el-Fasher," the spokesperson for the UN Secretary General told reporters in New York.

The Sudan Doctors Network, a medical group tracking the war, said fighters from the Rapid Support Forces on Tuesday “cold-bloodedly killed everyone they found inside the Saudi Hospital, including patients, their companions, and anyone else present in the wards.”

Sudanese residents and aid workers also described some of the atrocities carried out by the RSF, fighting since 2023 to take over Africa’s third largest nation, after they seized the army’s last stronghold in Darfur after over 500 days of siege.

RSF commander Gen. Mohammed Hamdan Dagalo on Wednesday acknowledged what he called “abuses” by his forces. In his first comments since the fall of el-Fasher, posted on the Telegram messaging app, he said an investigation was opened. He did not elaborate.

The RSF has been accused by the U.N. and rights groups of atrocities throughout the war, including a 2023 attack on another Darfur city, Geneina, where hundreds of people were killed.
