Sgt. Vadim Shyshimarin pleaded guilty to the charges during his trial in Kyiv on Wednesday. The 21-year-old soldier could get life in prison if convicted of shooting a Ukrainian man in the head through an open car window in a village in the northeastern Sumy region on Feb. 28, four days into the invasion.
Ukraine's Prosecutor General Iryna Venediktova has previously said her office was readying war crimes cases against 41 Russian soldiers for offenses including bombing civilian infrastructure, killing civilians, rape and looting.
It was not immediately clear how many of the suspects are in Ukrainian hands and how many could be tried in absentia.
