Ukrainian President Volodymyr Zelenskyy says he will meet U.S. President Donald Trump in Washington on Monday after a Russia-U.S. summit concluded without an agreement to stop the fighting in Ukraine after 3 1/2 years.

Canadian Prime Minister Mark Carney on Saturday welcomed what he said was U.S. openness to providing security guarantees to Ukraine under a peace deal to end Russia's war against Kyiv. "Robust and credible security guarantees are essential to any just and lasting peace.

Ukraine's President Volodymyr Zelenskiy said on Friday Russia continued attacking Ukraine ahead of a summit between Donald Trump and Vladimir Putin, but its attempt to demonstrate power by launching a new assault in the east failed.

Russia and Ukraine continued to exchange long-range drone and missile strikes on the eve of the summit. Ukraine’s military said on Friday morning that it had hit several targets inside Russia, including an oil refinery and a port that Moscow uses to import military supplies from Iran.
