The CEO of one of Ukraine’s largest power companies has asked people to stock up on warm clothing and blankets, warning that Russia’s assault on Ukraine’s power grid will lead to rolling blackouts throughout the winter. On Monday, the World Health Organization’s regional director for Europe, Dr. Hans Kluge, said Ukraine now faces its darkest days of the war so far.

Dr. Hans Kluge: “This winter will be life-threatening for millions of people in Ukraine. … Half of Ukraine’s energy infrastructure is either damaged or destroyed. This is already having knock-on effects on the health system and on the people’s health. Put simply, this winter will be about survival.”
