More than a million households are without electricity in Ukraine after a barrage of overnight Russian strikes hit energy and industrial infrastructure, officials said.
Ukraine's internal affairs minister, Ihor Klymenko, said five regions were hit and at least five people were injured, and work was under way to extinguish fires and restore supplies.
While Russian attacks on Ukrainian energy infrastructure have been common throughout the war, Moscow has intensified strikes as the country heads into winter.
It comes as US President Donald Trump's overseas envoy will travel to Germany this weekend to meet Ukrainian President Volodymyr Zelensky and European leaders for more talks on ending the war.
On Saturday, Zelensky said more than 450 drones and 30 missiles were used by Russia in overnight strikes. Klymenko said the Dnipropetrovsk, Kirovohrad, Mykolaiv, Odesa and Chernihiv regions were hit.
Russia's defence ministry said it used weapons including Kinzhal hypersonic missiles in the strikes - which are hard to track as they can change direction mid-flight.
