The 32-year-old American has been placed on Russia’s international wanted list and faces up to 10 years in prison if captured.

Kennedy secretly joined Ukraine’s International Legion in 2022 and served in the Kharkiv region during the early stages of Russia’s full-scale invasion, The Independent reported.

Several other foreign volunteers from countries including the US, UK, Sweden, Colombia and the Czech Republic have also been targeted by Russian courts.

The cases come as foreign volunteers continue to fight alongside Ukrainian forces. Colombian volunteers recently participated in an operation near Stepnohirsk in the Zaporizhzhia region, where Ukrainian forces used FPV drones and grenades to clear a Russian position.
