Trump's goodwill is being tested as Russian President Putin continues to pummel Ukrainian civilians and the U.S. pushes for a peace plan Moscow has yet to agree to.

U.S. President Donald Trump's envoy Steve Witkoff met President Vladimir Putin for three hours in Moscow on Friday to discuss the U.S. plan to end the war in Ukraine, and the Kremlin said the two sides' positions had moved closer.

Trump accused Zelensky of harming peace talks by not recognising Russian control of Crimea - a point of contention in bringing an end to the conflict. The Russian defence ministry claimed the deadly overnight strikes targeted Ukraine's military infrastructure, adding their aim had been "achieved".
