The investigators describe a desperate situation in one of Africa's largest countries. Two million civilians have fled from Sudan, and an additional eight million are on the run within the country.
They are fleeing indiscriminate aerial and artillery attacks that can strike anywhere; water and electricity supplies, schools, hospitals – no places seem safe.
"The warring parties are also attacking civilians with rape and other sexual violence, arbitrary arrests, and torture," the report states, presented in Geneva on Friday.
"These violations may constitute war crimes."
With tens of thousands dead, the conflict is on a similar level as, for example, the Gaza War, but the international community's engagement is much smaller. Chairman Mohamed Chande Othman says that the only hope of stopping the conflict is if an external military force intervenes "without delay".
The army and RSF were initially on the same side. RSF originated from the janjawid militia, which had a brutal role in the Darfur War in western Sudan in the 2000s.
The new war broke out after the leaders of the army and RSF fell out about a year ago.
