Moscow kept up its hammering of Ukraine’s energy grid in attacks that killed at least two people overnight to Sunday, according to Ukrainian officials. At least six people were wounded in the Dnipropetrovsk region, the emergency service said. Russia also targeted energy infrastructure in Odesa region, it said. A fire broke out and was promptly extinguished. Volodymyr Zelenskyy said on Telegram that repairing the country’s energy system remained challenging “but we are doing everything we can to restore everything as quickly as possible”. The Ukrainian president said two people were killed in overnight attacks across the country that struck Sumy, Kharkiv, Dnipro, Zaporizhzhia, Khmelnytskyi and Odesa and included more than 200 drones. The military said 30 strikes had been recorded across 15 locations. One person was killed in the second-largest city of Kharkiv, said mayor Ihor Terekhov.

Ukrainian drone strikes damaged energy networks in Russia-occupied parts of southern Ukraine, leaving hundreds of thousands of people without power, according to Kremlin-installed authorities there. More than 200,000 households in the occupied part of southern Ukraine’s Zaporizhzhia region had no electricity on Sunday, the Kremlin-installed local governor said. Nearly 400 settlements have had their supply cut because of damage to power networks from Ukrainian drone strikes, Yevgeny Balitsky said on Telegram.

Ukrainian crews have started repair works on the backup power line connecting the Zaporizhzhia nuclear power plant to the power grid, under a ceasefire brokered by the International Atomic Energy Agency, the Vienna-based UN organisation said on X post on Sunday. The fate of the plant – occupied by Russia and the largest in Europe – is a central issue in ongoing US-brokered peace talks.

Spanish prime minister Pedro Sánchez has said a US invasion of Greenland would make Russian president Vladimir Putin “the happiest man on Earth” in a newspaper interview. Sanchez said any military action by the US against Denmark’s Arctic territory would damage Nato and legitimise the invasion of Ukraine by Russia. “If we focus on Greenland, I have to say that a US invasion of that territory would make Vladimir Putin the happiest man in the world. Why? Because it would legitimise his attempted invasion of Ukraine,” Sanchez said in an interview in La Vanguardia newspaper published on Sunday. “If the United States were to use force, it would be the death knell for Nato. Putin would be doubly happy.“

Ukraine’s top negotiator said talks with US officials on ending the war with Russia would continue at the World Economic Forum opening this week in the Swiss resort of Davos. Rustem Umerov, writing on Telegram, said on Sunday that two days of talks in Florida with a US team including envoy Donald Trump’s envoy Steve Witkoff and son-in-law Jared Kushner had focused on security guarantees and a postwar recovery plan for Ukraine.
