Damage to power infrastructure from a wave of Russian missile strikes has led to emergency power outages in most regions across Ukraine, Energy Minister Herman Halushchenko said.
"Today, the enemy attacked the country's power generation facilities and power grids again," Halushchenko said on Facebook. "There are attacks in Kharkiv, Lviv, Ivano-Frankivsk, Zaporizhzhia, Vinnytsia and Kyiv regions."
"The next days will be difficult. Power engineers are already working to restore electricity supply," the energy minister continued.
Saturday's wave of missile attacks follows a relative lull that had allowed Ukrainian power companies to reduce the power deficit caused by damage to transformers and substations.
