Russia-Ukraine war live: Zelenskiy vows to keep up fight amid new wave of Russian missile attacks

President says his only wish for 2023 is victory for Ukraine, while Vladimir Putin says Russia will ‘never give in’ to the west

Russian forces are probably depleting their stocks of artillery ammunition and as a result will struggle to support their current pace of operations on parts of the frontline in Ukraine, according to the Institute for the Study of War.

The US thinktank said in an update on Sunday that the constraints on munitions would likely contribute in preventing Russian forces from maintaining a high operational pace in the heavily contested Bakhmut area of eastern Ukraine in the near term.
