KYIV (Reuters) - Ukrainian authorities on Friday gradually restored power, aided by the reconnection of the country's four nuclear plants, but millions of people were still in the dark after the most devastating Russian air strikes of the war.

President Volodymyr Zelenskiy pleaded with Ukrainians to use energy sparingly. "If there is electricity, this doesn't mean you can turn on several powerful electrical appliances at once," he said in an evening video address.
