Speaking to the BBC about the ICC investigation, Khan said: “We have now found concrete evidence linking what is happening on the ground to specific people in leadership mode and through linkage evidence.”
But she did not say when charges would be brought against those responsible for atrocities in the war, which began in April 2023.
“I can’t tell you how soon or how long it will take,” she said.
“But I can say that we have made significant progress and achieved breakthroughs.”
The ICC, headquartered in The Hague, Netherlands, is an international court with the power to prosecute genocide, crimes against humanity and war crimes.
Khan spoke to the BBC after visiting a refugee camp in eastern Chad. There, people fleeing the fighting in Darfur told her about the atrocities they had suffered.
Tens of thousands of people have been forced to flee their homes in El Fasher, and the United Nations said the violence there bore “the hallmarks of genocide.”
RSF denied widespread claims that the killings in the city were racially motivated and followed the pattern of Arab paramilitaries targeting non-Arab populations.
The group claimed the scale of the atrocities had been exaggerated but acknowledged that some violations had occurred in the city.
Shortly after el-Fasher’s arrest, RSF leader General Mohamed Hamdan Dagalo said the group was investigating the atrocities. RSF recently said an investigation was ongoing.
Eleanor Sanders, the UK’s human rights ambassador, recently warned that the city of El-Obeid could face atrocities similar to those seen in El-Fasher last year.
The United Nations Human Rights Council on Monday ordered an urgent investigation into allegations of crimes committed during the fighting in El Obeid.
