Zelenskyy’s office had said teams were making arrangements for the leaders to talk again Saturday, but Trump went directly to the Rome airport after the funeral and boarded Air Force One for the 10-hour flight back to the United States, which seemed to rule out a second in-person conversation.

The White House said their discussion was “very productive” and that more details would be released later. The meeting lasted about 15 minutes inside St. Peter’s Basilica at the Vatican just before they took their seats for the outdoor funeral service.

Zelenskyy said “good meeting” on social media after the funeral.

“We discussed a lot one on one. Hoping for results on everything we covered. Protecting lives of our people. Full and unconditional ceasefire. Reliable and lasting peace that will prevent another war from breaking out,” he wrote. “Very symbolic meeting that has potential to become historic, if we achieve joint results. Thank you.”

The meeting took place hours after Trump said on social media, after he arrived in Italy late Friday, that Russia and Ukraine should meet for “very high level talks” on ending the three-year war sparked by Russia’s invasion.

Trump has pressed both sides to agree to a ceasefire. His special envoy, Steve Witkoff, had met earlier Friday with Russian President Vladimir Putin in Moscow, and Trump said both sides were “very close to a deal.”

Putin did not attend Francis’ funeral. He faces an arrest warrant issued by the International Criminal Court, which has accused him of war crimes stemming from Moscow’s invasion of Ukraine.

Meanwhile, in a statement Friday night, Zelenskyy said “very significant meetings may take place” in coming days, and that an unconditional ceasefire was needed.

“Real pressure on Russia is needed so that they accept either the American proposal to cease fire and move towards peace, or our proposal — whichever one can truly work and ensure a reliable, immediate, and unconditional ceasefire, and then — a dignified peace and security guarantees,” he said.

“Diplomacy must succeed. And we are doing everything to make diplomacy truly meaningful and finally effective.”

There was no immediate word on whether Trump and Zelenskyy spoke again after they paid their respects to the pope, who had repeatedly pressed for an end to the conflict.
