The resumption of U.S. military and intelligence aid for Ukraine follows a contentious White House meeting between the American and Ukrainian leaders, but Moscow is unlikely to agree to the proposed ceasefire.

The Kremlin said on Wednesday it was awaiting details from Washington about a proposal for a 30-day ceasefire in Ukraine before responding, while U.S. Secretary of State Marco Rubio hoped a deal would be struck within days.

Ukraine yesterday agreed to a temporary ceasefire with Russia after negotiators met in Saudi Arabia. The solution to this war and the way to end it and to achieve the president's objective of peace is to negotiate. But before you can negotiate, you have to stop shooting at each other.

Ukraine’s consent to a 30-day ceasefire proposal has handed the Kremlin a difficult challenge at a time when its military has an upper hand in the war.

Kyiv has seized the diplomatic initiative but Russia retains the advantage on the battlefield, having chewed through Ukrainian land.
