Ukrainian President Volodymyr Zelenskyy urged the United Nations this week to condemn Russia's ramped up bombing campaign that has left millions of people without energy supplies, including heat and water in below-freezing temperatures.Russian missiles this week hit energy and civilian infrastructure throughout the country, causing blackouts in the capital Kyiv and other major cities."When the temperature is below zero outside, and tens of millions of people are left without electricity, heat and water as a result of Russian missiles hitting energy facilities, this is an obvious crime against humanity," Zelenskyy said.Ukrainian Emergency Services said officials responded to 159 incidents throughout multiple regions and detected and removed 1,453 explosive objects on Wednesday alone.The country is working to restore power in several regions, but the work is "taking longer than previous attacks," because the Wednesday attack directly targeted power generation facilities, Ukraine's national company Ukenergo said, according to the outlet."
