Ukrainian President Volodymyr Zelensky said Tuesday that Ukraine had accepted a 30-day ceasefire proposed by the United States, following critical peace talks between US and Ukrainian officials in Saudi Arabia.

The ceasefire proposal accepted by Ukraine covers the entire front line of the fighting with Russia, not just the air and sea, Zelensky said after the more than eight-hour long meeting.

“Ukraine accepts this proposal, we consider it positive, we are ready to take such a step, and the United States of America must convince Russia to do so,” Zelensky said, adding that the ceasefire would start the moment Moscow agrees to it.

The United States said in a joint statement with Ukraine following the meeting in Jeddah that it would “immediately lift the pause on intelligence sharing and resume security assistance to Ukraine.” A Ukrainian official confirmed on Tuesday that US security assistance to Ukraine had resumed.

US Secretary of State Marco Rubio said immediately after the meeting that the onus is now on Russia to take steps to end the war. “We hope that they’ll say yes, that they’ll say yes to peace. The ball is now in their court,” he said of the Russians.

US President Donald Trump later welcomed the news and vowed to speak with Russian President Vladimir Putin about the plan, potentially this week.

On Wednesday, Zelensky said he believes Kyiv “can expect” the US to take “strong steps” against Russia if Moscow was to reject the ceasefire proposal.
