Ukraine’s President Volodymyr Zelensky says Russia may be planning more attacks on the country’s energy infrastructure as rolling blackouts become part of everyday life for 4.5 million Ukrainians. Kyiv mayor Vitali Klitschko also warned the city’s residents they may need to temporarily leave their homes if there is a total power outage or further disruptions to the local water supply. With winter fast approaching, freezing temperatures and the prospect of months without heating are serious concerns. Local authorities have been planning to roll out 1,000 heating points in case of a city-wide failure, which would rely on generators, and provide other vital resources, including water. But ongoing Russian drone and missile attacks are impeding those efforts, with about 40% of Ukraine’s energy infrastructure damaged in recent weeks. Klitschko says people “need to be prepared” for the worst-case scenario and labelled Russia’s attacks “genocide”.
