Russia's Defence Ministry has released what it describes as "chilling" video evidence of a drone it claims was part of a large-scale Ukrainian attempt to strike one of President Vladimir Putin's residences in the Novgorod region, near Lake Valdai, on the night of December 28-29, 2025. The footage, filmed at night, shows a damaged drone lying in snowy woodland, with a Russian serviceman pointing to fragments of what Moscow identifies as a Ukrainian Chaklun-V drone carrying a 6-kg unexploded explosive charge. The ministry claims 91 long-range drones were launched from Ukraine's Sumy and Chernihiv regions in a "carefully planned" operation, all of which were intercepted by Russian air defences, resulting in no damage or injuries.
