Ukrainian President Volodymyr Zelenskiy has met U.S. President Donald Trump in the Italian capital, where both leaders were attending the funeral of Pope Francis, a spokesman for Zelenskiy said.
No details were provided of the meeting, but it comes at a critical time in negotiations aimed at bringing an end to fighting between Ukraine and Russia.
Trump, who has been pressing both sides to agree a ceasefire, said on Friday that there had been productive talks between his envoy and the Russian leadership, and called for a high-level meeting between Kyiv and Moscow to close a deal.
Trump had previously warned both sides his administration would walk away from its efforts to achieve a peace if the two sides do not agree a deal soon.
The meeting in Rome is the first face-to-face encounter between Trump and Zelenskiy since an Oval Office meeting in February that turned into a shouting match.
Following that meeting, the United States cut off intelligence cooperation with Ukraine, which is critical to its efforts to stave off Russian attacks, though this was later restored.
