Joe Biden has apologised publicly to the Ukrainian president, Volodymyr Zelenskiy, for the months of delay in American military assistance that allowed Russia to make gains on the battlefield, and announced a further $225m (£177m) in military aid to Ukraine.
Meeting Zelenskiy in Paris on Friday, the US president told him: “You haven’t bowed down, you haven’t yielded at all, you continue to fight in a way that is … just remarkable. We are not going to walk away from you.”
