Russia unleashed its second big attack on Ukraine's energy infrastructure this month on Thursday, cutting power to more than 1 million people in the west, south, and center of the country.
Lviv regional governor said Russian strikes had cut off electricity to about 523,000 people in the western region adjoining Poland.
Power was also cut to nearly 500,000 people in the Volyn and Rivne regions, their governors said, and disrupted in the Khmelnytskyi and Zhytomyr regions.
The attack reinforced fears of long power cuts during the winter months as temperatures across Ukraine hover around zero.
