Ukraine president and Nato chief say attack likely to hamper peace negotiations as temperatures continue to plummet. What we know on day 1,442

Senior Ukrainian and Russian officials are due to meet in Abu Dhabi on Wednesday for a second round of talks brokered by the Trump administration. The two-day talks are expected to mirror last month’s format, with negotiators from Washington, Kyiv and Moscow in attendance. Donald Trump has struck an upbeat tone in recent weeks, saying that an end to the four-year war is within reach. However, Moscow and Kyiv have tempered expectations, playing down the prospects of an immediate breakthrough. If the talks fail again, the four-year war is likely to continue until one side reaches a breaking point and is forced to give in.

Russia launched the “most powerful” attack this year on Ukraine’s battered energy facilities overnight, Kyiv said on Tuesday. Ukraine said Russia had attacked with 71 missiles and 450 attack drones. Six people were wounded in the capital, officials said, and a drone strike on the southern city of Zaporizhzhia also killed two teenagers and wounded at least 11 people. Russia’s defence ministry said it had launched “a massive strike” against “Ukrainian military-industrial complex enterprises and energy facilities”.
