Russian President Vladimir Putin held a phone call with US President Donald Trump on Sunday, during which he congratulated him on his 80th birthday and discussed bilateral relations between Moscow and Washington, according to the Kremlin.

During the conversation, which lasted just under an hour, Trump once again called for an end to the war in Ukraine, Kremlin aide Yri Ushakov said.

They also agreed that US envoys Steve Witkoff and Jared Kushner would visit Russia again in the near future, Ushakov said. Putin told Trump that if Ukrainian President Volodymyr Zelensky wants a meeting, he should come to Moscow – an offer that Zelensky has consistently rejected.

Trump informed Putin that an agreement in the war between the US and Iran is imminent and may be announced later Sunday, the Kremlin handout said.

CNN has reached out to the White House for comment.
