In its first report, the Commission of Human Rights Experts on Ethiopia said it had found evidence of a wide range of violations in the country by all sides since fighting erupted in the northern Tigray region in November 2020.
The commission, created by the UN Human Rights Council last year and made up of three independent rights experts, said it had "reasonable grounds to believe that, in several instances, these violations amount to war crimes and crimes against humanity".
UN investigators said they believed Ethiopia's government was behind ongoing crimes against humanity in the Tigray region, and warned that the resumption of the conflict there increased the risk of "further atrocity crimes".
The experts highlighted the horrifying situation in Tigray, where the government and its allies have denied around six million people access to basic services, including the internet and banking, for over a year, and where severe restrictions on humanitarian access have left 90 percent of the population in dire need of assistance.
The report said there were "reasonable grounds to believe that the Federal Government and allied regional State governments have committed and continue to commit the crimes against humanity of persecution on ethnic grounds and other inhumane acts." They were "intentionally causing great suffering or serious injury to body or to mental or physical health based on their ongoing denial and obstruction of humanitarian assistance to Tigray," the report said.
