Zelensky Takes Aim at Hidden Enemy: Ukrainians Aiding Russia
KYIV, Ukraine — Even as it engages in fierce fighting with Russia on the battlefield, Ukraine is also waging war on a different, more shadowy front: rooting out spies and collaborators in government and society who are providing crucial help to the invading forces.

While Ukrainian society as a whole has rallied to the country’s defense, Russian sympathizers are reporting the locations of Ukrainian targets like garrisons or ammunition depots, Ukraine’s officials say. Priests have sheltered Russian officers and informed on Ukrainian activists in Russian-occupied areas. One official said collaborators had removed explosives from bridges, allowing Russian troops to cross.

The issue was cast into sharp relief on Sunday night when President Volodymyr Zelensky dismissed two senior law enforcement officials, saying they had not been nearly aggressive enough in weeding out traitors. It was the first major reshuffle of his brain trust since the war began.
