President Volodymyr Zelensky on Sunday said Russia was responsible for sweeping electricity cuts across east Ukraine, accusing Moscow of having deliberating hit civilian infrastructure.
"A total blackout in the Kharkiv and Donetsk regions, a partial one in the Zaporizhzhia, Dnipropetrovsk and Sumy regions," Zelensky said in a statement on social media, blaming "Russian terrorists".
"No military facilities," he added. "The goal is to deprive people of light and heat."
