People in the Ukrainian capital Kyiv had to queue for water after Russian missiles struck key facilities across the country on Monday.
An evening update from the city’s mayor, Vitaliy Klitschko, said 40% of consumers in Kyiv remained without water, and 270,000 homes had no power.
Thirteen people were injured in the attacks nationwide, Ukraine said.
Russia said the strikes were aimed at Ukraine’s military control and energy systems, and that all targets were hit.
But the Ukrainian military said it had shot down 45 out of 55 missiles that were launched.
