Russia has launched its most powerful blow against Ukraine's energy sector so far this year, according to the private energy company, DTEK. The combined missile and drone strikes which targeted power plants and infrastructure in Kyiv and multiple locations left the system operating with serious restrictions, it said. The strikes were launched as temperatures dropped to -20C (-4F) and left more than 1,000 tower blocks in the capital without heating once again and damaged a power plant in the eastern city of Kharkiv beyond repair. President Volodymyr Zelensky said Russia was choosing terror and escalation rather than diplomacy to end this war and called for maximum pressure on Moscow from Ukraine's allies. The attack comes after a so-called energy truce agreed by Donald Trump with Vladimir Putin expired at the weekend.

Twelve miners have been killed by a Russian drone strike in eastern Ukraine, the country's largest private energy firm has said. DTEK said a bus carrying workers after a shift in the Dnipropetrovsk region had been targeted in Sunday's attack. At least seven people were injured. Earlier, at least two others were killed and nine injured in separate Russian attacks overnight and on Sunday. The victims included six people hurt when a drone hit a maternity hospital in Zaporizhzhia.

Ukrainians brace for -20C despite energy truce: 'It will be a catastrophe' It's not the electricity cuts that Yulia Hailunas struggles with most after the Russian airstrikes. Like so many Ukrainians, she's had no central heating since Russia launched a wave of targeted attacks on the power grid in January. So Yulia now lives in a long, quilted coat and hat in her flat, and rests her feet on a saucepan-full of hot water to keep them from freezing. If that's not enough, she lifts weights for 10 minutes to get warm. When the weather outside is above zero, it's just about bearable.
