Ukrainian forces retaliated against a massive Russian attack by striking power plants in Klintsy, Bryansk region, and Belgorod last night, resulting in power outages. The strikes occurred in response to widespread Russian military actions that took place on October 5th. According to a report from X user Tendar, the Ukrainian strikes targeted energy infrastructure. The exact timing of these retaliatory actions is not specified beyond "last night," but they followed extensive Russian assaults across Ukraine. Previous reports detailed a significant Russian overnight offensive involving 549 drones and missiles. This offensive resulted in civilian casualties, including the deaths of a teenager and her family in Lapaivka village, Lviv oblast, when their home was destroyed. Euromaidan Press reported five deaths and 10 injuries nationwide during that period.
