The New Yorker recently published a report from Sudan, headlined “Escape from Khartoum.” The contributor Nicolas Niarchos journeyed for days through a conflict to reach a refugee camp in the Nuba Mountains, where members of the country’s minority Black ethnic groups are seeking safety, but remain imperilled by hunger. The territory is “very significant to the Nuba people,” Niarchos explains to David Remnick. “They feel safe being there because they have managed to resist genocide before by hiding in these mountains. And then you start seeing the children with their distended bellies, and you start hearing the stories of the people who fled.” The civil war pits the Sudanese Army against a militia group called the Rapid Support Forces. Once allies in ousting Sudan’s former President, the Army and the R.S.F. now occupy different parts of the country, destroying infrastructure in the opposing group’s territory, and committing atrocities against civilians: killing, starvation, and widespread, systematic sexual violence. The warring parties are dominated by Sudan’s Arabic-speaking majority, and “there’s this very, very toxic combination of both supremacist ideology,” Niarchos says, and “giving ‘spoils’ to troops instead of paying them.” One of Niarchos’s sources, a man named Wanis, recalls an R.S.F. soldier telling him, “If you go to the Nuba Mountains, we’ll reach you there. You Nuba, we’re supposed to kill you like dogs.”
