Russia has so far refused to agree to a face-to-face meeting between Zelensky and Putin, despite several requests from Kyiv. The Kremlin hasn't ruled out summits for the two leaders but has said they could only meet in the very final stages of clinching a peace agreement.

The Ukrainian president says Monday's talks have been "constructive" as European leaders repeat calls for a ceasefire.

President Trump, Ukrainian President Volodymyr Zelensky and key European leaders met at the White House on Monday afternoon to discuss Russia's war in Ukraine.
