Ukrainian President Volodymyr Zelenskyy told NATO leaders on Wednesday his country needed more weapons and money to defend itself against Russia, warning that Moscow's ambitions did not stop at Ukraine.

"This is not a war being waged by Russia against only Ukraine. This is a war for the right to dictate conditions in Europe - for what the future world order will be like," he said in a virtual address to a summit of the Western defense alliance in Madrid.
