The United Nations Wednesday named three human rights experts who will make up an independent panel tasked with probing possible war crimes in Ukraine. The panel is specifically looking at accusations of indiscriminate bombardment of civilians by Russia.

The UN Human Rights Council agreed to establish the independent panel at the request of Ukraine, the European Union, Britain, and the United States. Ukraine and its allies have alleged that Russian armed forces killed civilians by shelling and besieging cities, most notably Mariupol, the southern port. Erik Mose of Norway will lead the independent panels investigation into alleged human rights abuses and violations of international humanitarian law in the context of the aggression against Ukraine by the Russian Federation. The other panel members include Jasminka Dzumhur, the human rights ombudsperson of Bosnia and Herzegovina, and Pablo de Greiff of Colombia. The panel will investigate by interviewing witnesses and collecting forensic material for any future legal proceedings.

Russia denies all allegations and continues to call the invasion a special operation to “denazify” Ukraine.
