A Russian court on Monday sentenced a 72-year-old American in a closed trial to nearly seven years in prison for allegedly fighting as a mercenary in Ukraine. Prosecutors said Stephen Hubbard signed a contract with the Ukrainian military after Russia sent troops into Ukraine in February 2022 and he fought alongside them until being captured two months later.

Hubbard was captured less than two months later, according to Russian state media outlet RIA Novosti. In a closed trial on Monday, Hubbard stood handcuffed inside a glass cell and removed a hat from his shaven head as a judge pronounced him guilty.

Stephen Hubbard, who moved to Ukraine in 2014, was captured by Russian soldiers in Izyum in April 2022, and was charged with serving in a territorial defense unit.
