(Reuters) – Rebels and government troops in Congo have committed atrocities including mass rape, cannibalism and the dismemberment of civilians, according to testimony published on Tuesday by a team of U.N. human rights experts who said the world must pay heed. The team investigating a conflict in the Kasai region of Democratic Republic of Congo told the U.N. Human Rights Council last week that they suspected all sides were guilty of war crimes and crimes against humanity. Their detailed 126-page report cataloged gruesome attacks committed in the conflict, which erupted in late 2016, involving the Kamuina Nsapu and Bana Mura militias and Congo’s armed forces, the FARDC.
