Russian forces have intensified attacks on Ukraine’s second-largest city, Kharkiv, striking amid freezing winter temperatures and killing at least four people, including three children, according to Ukrainian authorities. Regional officials say glide bombs hit residential areas in the Kharkiv region for a second consecutive day, leaving homes destroyed and civilians injured. As Kharkiv burns under renewed bombardment, Russia also claimed it intercepted a Ukrainian drone targeting energy infrastructure in the Volgograd region, underscoring the widening scope of the war. The latest violence comes as civilian casualties continue to mount nearly four years into the conflict, with the UN warning that 2025 has been the deadliest year since the invasion began.
