A 21-year-old Russian soldier facing the first war crimes trial since Moscow invaded Ukraine pleaded guilty Wednesday to killing an unarmed civilian.

Sgt. Vadim Shishimarin could get life in prison for shooting a a 62-year-old Ukrainian man in the head through an open car window in the northeastern Sumy region on Feb. 28, four days into the invasion.

Shishimarin, a captured member of a Russian tank unit, was prosecuted under a section of the Ukrainian criminal code that addresses the laws and customs of war.
