Millions of Ukrainians are enduring cold temperatures and darkness after a wave of Russian attacks against energy facilities caused widespread power outages across the country. The large scale of the damage will take time to restore energy flows. Electricity supplies across Ukraine are being rationed and people in Kiev went without power for 10-12 hours. Russia's attack was "one of the largest direct ballistic attacks on energy facilities" since the start of the war. Emergency power cuts were implemented across almost all regions to stabilise the network. "We then switched to hourly power cuts, so that consumers could more easily plan their activities around the outages," said a Ukrainian spokesperson. The attack came just as temperatures in Ukraine began to drop to single digits degrees Celsius. Russia has targeted Ukraine's energy infrastructure on numerous occasions since it launched its full-scale invasion in 2022, increasing attacks against them at winter time.
