U.S. President Donald Trump said he and Russian President Vladimir Putin did not reach a deal to end Russia’s war in Ukraine after talks in Alaska on Friday, as the two leaders offered scant details on what was discussed but heaped praise on one another.

Putin said he and Trump had reached an “understanding” on Ukraine and warned Europe not to “torpedo the nascent progress.” But Trump said, “There’s no deal until there’s a deal” and said he plans to speak with Ukrainian President Volodymyr Zelenskyy and European leaders soon.

The high-profile summit ended without an agreement to end, or even pause, the brutal conflict — the largest land war in Europe since 1945 — which has raged for more than three years.
