The Ukrainian president Volodymyr Zelenskyy said his country did not get any early warning from US allies about last night’s Russian ballistic missile strikes on Kyiv which caused widespread damage.
Ukrainian officials say they fear the US has also begun withholding essential air defence supplies – which have already been paid for by Europe.
Mr Zelenskyy said the latest barrage had hit critical energy infrastructure – leaving more than half a million people without power or running water.
