Russian strikes have resulted in widespread power outages and disruptions to water supply in northern Ukraine, with an increase in civilian casualties in the eastern region, Ukrainian authorities reported on Saturday. In the Sumy region, close to the Russian border, strikes late Friday damaged energy infrastructure, leaving more than 100,000 households without electricity, according to the Ukrainian Energy Ministry. Russian drones later targeted the city of Sumy, hitting power lines connected to the water pumping system, leading to a cut-off in water supply.
