Tens of thousands of people have been killed in the Sudanese city of Al Fashir by the Rapid Support Forces (RSF) in a two-day window after the paramilitary group captured the regional capital, analysts believe.

Sky News is not able to independently verify the claim by Yale Humanitarian Labs, as the city remains under a telecommunications blackout.

Stains and shapes resembling blood and corpses can be seen from space in satellite images analysed by the research lab.

Nathaniel Raymond, executive director of Yale Humanitarian Labs, said: “In the past 48 hours since we’ve had [satellite] imagery over Al Fashir, we see a proliferation of objects that weren’t there before RSF took control of Al Fashir – they are approximately 1.3m to 2m long which is critical because in satellite imagery at very high resolution, that’s the average length of a human body lying vertical.”

Mini Minawi, the governor of North Darfur, said on X that 460 civilians have been killed in the last functioning hospital in the city.

The Sudan Doctors Network has also shared that the RSF “cold-bloodedly killed everyone they found inside Al Saudi Hospital, including patients, their companions, and anyone else present in the wards”.

World Health Organisation (WHO) chief Dr Tedros Adhanom Ghebreyesus said it was “appalled and deeply shocked” by the reports.

Satellite images support the claims of a massacre at Al Saudi Hospital, according to Mr Raymond, who said YHL’s report detailed “a large pile of them [objects believed to be bodies] against a wall at one building at Saudi hospital. And we believe that’s consistent with reports that patients and staff were executed en masse”.

In a video message released on Wednesday, RSF commander Mohamed Hamdan Dagalo acknowledged “violations in Al Fashir” and claimed “an investigation committee should start to hold any soldier or officer accountable”.

The commander is known for committing atrocities in Darfur in the early 2000s as a Janjaweed militia leader, and the RSF has been accused of carrying out genocide in Darfur 20 years on.

Sources have told Sky News the RSF is holding doctors, journalists and politicians captive, demanding ransoms from some families to release their loved ones.

One video shows a man from Al Fashir with an armed man kneeling on the ground, telling his family to pay 15,000. The currency was not made clear.

In some cases, ransoms have been paid, but then more messages come demanding that more money be transferred to secure release.

Muammer Ibrahim, a journalist based in the city, is currently being held by the RSF, who initially shared videos of him crouched on the ground, surrounded by fighters, announcing his hometown had been captured under duress.

He is being held incommunicado as his family scrambles to negotiate his release. Muammer courageously covered the siege of Al Fashir for months, enduring starvation and shelling.

The Committee to Protect Journalists regional director Sara Qudah said the abduction of Muammar Ibrahim “is a grave and alarming reminder that journalists in Al Fashir are being targeted simply for telling the truth”.
