More than 1,000 civilians were killed in a three-day attack by the Rapid Support Forces paramilitary group earlier this year on the largest displacement camp in western Sudan, the U.N. Human Rights Office said in a report released Thursday. RSF stormed Zamzam camp in April as part of its siege of the city of el-Fasher, the provincial capital of North Darfur province. In the attack, hundreds of people were summarily executed, according to the report. People were killed in house-to-house raids and the main market, as well as in schools and health facilities. The report detailed patterns of sexual violence, “including rape and gang rape, and sexual slavery.” The report called it “a consistent pattern of serious violations of international humanitarian law and gross abuses of international human rights law.” It comes a few weeks after Amnesty International accused the RSF of committing war crimes in their attack of the camp.
