A U.N. body has told Reuters that Rwanda-backed M23 rebels attacked civilians in east Democratic Republic of Congo, killing 169 people earlier this month. Speaking to Reuters, the group’s leader called the report a “smear campaign.” This is the first time the U.N. is reporting on the M23’s attack, as President Trump is pushing for a peace deal between Congo and Rwanda, which would allow the U.S. to tap the DRC’s rich mineral resources.
