Ukraine claims that power and water supplies across the country have been hit after Russia launched 50 missiles targeting critical facilities.
80 per cent of residents in the capital Kyiv have been left without water and around 350,000 apartments have been left with no electricity, Mayor Vitali Klitschko has said.
Russia says that its high-precision weaponry has targeted Ukraine's military command and energy systems. The country's defence ministry added that "all designated objects were hit".
Klitschko reported water shortages in Kyiv after an energy facility near the city had been damaged in the Russian strike. He said the supply would be partially restored within hours.
He also confirmed that engineers were urgently deployed to restore the electricity supply in the city.
The area's authorities said that "no hits were recorded" in Kyiv due to the "effective work of the air defence forces".
A total of 18 facilities were hit in the 10 regions of Ukraine with cities such as Kharkiv and Lviv also targeted.
Residents in the areas under attack were urged to remain in shelters amid fears that further strikes could follow.
Ukrainian Foreign Minister Dmytro Kuleba said that Russia "fights civilians" rather than "on the battlefield".
The strikes are the latest in a wave of deadly missile and drone attacks in recent weeks - which have reportedly destroyed nearly a third of Ukraine's power stations ahead of the winter.
