Putin forces intensify strikes on civilian areas as Zelenskiy issues furious rebuke to Nato over no-fly zone refusal

• Russia-Ukraine war: live news

The US envoy to the UN said the world had narrowly averted a nuclear catastrophe in Russia’s attack on Europe’s largest nuclear power plant, as Moscow’s forces intensified their devastating campaign of artillery and airstrikes against civilian areas of Ukraine.

Linda Thomas-Greenfield, speaking at an emergency meeting of the UN security council in New York on Friday, the US envoy said Russia’s actions, which caused a major fire at the Zaporizhzhia compound, reflected a “dangerous new escalation” in its invasion of Ukraine. “Russia’s attack last night put Europe’s largest nuclear power plant at grave risk,” she said. “It was incredibly reckless and dangerous. And it threatened the safety of civilians across Russia, Ukraine and Europe.”
