U.S. officials were in Moscow for talks, and the Russian leader said he was open to a cease-fire, but President Volodymyr Zelensky of Ukraine expressed skepticism.

Ukrainian President Volodymyr Zelenskiy said on Friday that he saw a good chance to end the war with Russia after Ukraine accepted a U.S. proposal for a 30-day interim ceasefire and Moscow said it would only agree if certain conditions were met.

U.S. President Donald Trump said Friday that White House officials had a “very good” conversation with Russia’s President Vladimir Putin the day before and suggested it could help bring an end to the war in Ukraine.
