Ukraine has declared emergency power outages across almost all regions following a sustained campaign of Russian missile and drone strikes targeting its energy infrastructure. This marks the fourth consecutive winter of blackouts since Russia's full-scale invasion began in February 2022. The Ukrainian energy ministry indicated that only the eastern Donetsk region is exempt from these outages, while the northern Chernihiv region is already experiencing hourly power cuts. In response to the attacks, Ukraine has ramped up its own strikes on Russian oil refineries, including a significant drone attack on an oil depot in Crimea, which has resulted in extensive damage and ongoing fires. These developments have led to fuel shortages and rising prices in Russia, potentially impacting its military operations. As temperatures drop, the situation remains critical for millions of civilians affected by the outages, with Ukrainian President Volodymyr Zelensky accusing Russia of using energy strikes as a means of psychological warfare.
