Kyrylo Budanov arrives in US heading delegation for further talks on peace proposals. What we know on day 1,425Russia is taking aim at Ukraine’s nuclear power system, Volodymyr Zelenskyy said on Sunday, as the Kremlin continues to try to freeze Ukraine into submission by crippling its energy grid. “We do not see any willingness on the part of the aggressor to comply with any agreements or end the war,” the Ukrainian president said. “Instead, there is ample information about preparations for further Russian strikes on our energy sector and infrastructure, including facilities and networks that serve our nuclear power plants. Each such Russian strike on the energy sector amid such a harsh winter weakens and undermines the efforts of key states – in particular the United States – to end this war.”Zelenskyy spoke after a briefing from Ukraine’s chief of defence intelligence, Oleh Ivashchenko – the recent replacement for Kyrylo Budanov, who was made head of the president’s office. Budanov on Saturday confirmed his own arrival in the US to discuss peace proposals. He and Ukrainian negotiators Rustem Umerov and Davyd Arakhamia would meet with US envoy Steve Witkoff, Jared Kushner and the US army secretary, Dan Driscoll, Budanov said. Zelenskyy has tasked his delegation at the Miami talks with finalising proposals about security guarantees and economic recovery. If American officials approve the proposals, the US and Ukraine could sign a deal next week at the World Economic Forum in Davos, Switzerland, according to Zelenskyy. However Russia has given no indication it will accept any peace deal without Ukraine’s entire Donbas region being handed over for a start.
