MOSCOW—A court in Moscow upheld a 19-year prison sentence Tuesday for imprisoned Russian opposition leader Alexei Navalny, who was convicted on charges of extremism in August.
Navalny was found guilty on charges related to the activities of his anti-corruption foundation and statements by his top associates. It was his fifth criminal conviction and his third and longest prison term—all of which his supporters see as a deliberate Kremlin strategy to silence its most ardent opponent.
