President Volodymyr Zelensky says Ukraine has been hit by the biggest ever aerial attack from Russia, after 728 drones and 13 cruise or ballistic missiles struck cities around the country in multiple waves.

Zelensky condemned the "telling attack", adding: "It comes precisely at a time when so many efforts have been made to achieve peace, to establish a ceasefire, and yet only Russia continues to rebuff them all."

The overnight strike came after President Donald Trump said the US would send more weapons to Kyiv - a reversal of last week's suspension which US media said Trump had not known about.

On Tuesday, the US leader expressed growing frustration at Russian President Vladimir Putin.

"We get a lot of bullshit thrown at us by Putin, if you want to know the truth," Trump told reporters. "He's very nice to us all the time, but it turns out to be meaningless."

Kremlin spokesman Dmitry Peskov said Moscow was "pretty calm about this. Trump's way of talking is generally quite harsh, the phrases he uses."

The two leaders have been in regular contact but this has so far failed to translate into tangible steps towards a ceasefire in Ukraine - something Trump once said he would be able to achieve in a day.

Last week, following a phone call with the Russian president, Trump said he was "very unhappy".

"He wants to go all the way, just keep killing people, it's no good," Trump said of Putin.

The criticism came even as the Trump administration announced a suspension of military aid to Ukraine, reportedly authorised by US Defence Secretary Pete Hegseth and Elbridge Colby, the under-secretary of defence for policy.

Asked by reporters on Tuesday who had taken the decision, Trump - sitting right next to Hegseth - replied: "I don't know. Why don't you tell me?"

The reversal of the decision may now mean that 10 Patriot missiles may
