US President Donald Trump and Ukrainian President Volodymyr Zelensky held crunch war talks in the heart of the Vatican minutes before the start of the funeral of Pope Francis on Saturday, as the White House mounts an increasingly urgent push to strike a peace deal in Ukraine.

The office of Zelensky shared a picture of Trump and Zelensky engaged in conversation at St. Peter’s Basilica.

Trump said Saturday that he doubts Russia’s Vladimir Putin wants to end his war in Ukraine, expressing new skepticism that a peace deal can be reached soon.
