Ukraine has sentenced three men to 15-year prison terms for war crimes and collaboration with Russia. The crimes included repairing Russian military equipment – specifically a tank and artillery – and deliberately targeting civilians with bombs. Ukrainian intelligence identified two of the men through their online activity in chat groups, revealing links to Russian intelligence. The third individual was implicated through a family connection to Russia’s domestic security service. These convictions highlight Ukraine’s ongoing efforts to prosecute those accused of aiding the Russian invasion. The cases demonstrate the use of both digital surveillance and traditional intelligence gathering to identify and prosecute collaborators. Ukraine continues to investigate and pursue individuals allegedly involved in supporting Russian aggression.
