The Trump administration has suspended delivery of all US military aid to Ukraine, blocking billions in crucial shipments as the White House piles pressure on Ukraine to sue for peace with Vladimir Putin.

The decision affects deliveries of ammunition, vehicles, and other equipment including shipments agreed to when Joe Biden was president.

It comes after a dramatic blow-up in the White House on Friday during which Donald Trump told Volodymyr Zelenskyy that he was “gambling with” a third world war. The Ukrainian president was told to come back “when he is ready for peace”.
