Ukraine will share a revised peace plan with the U.S. on Tuesday that is aimed at ending Russia's war, after talks in London between President Volodymyr Zelenskiy and the leaders of France, Germany and Britain.

KYIV, Ukraine -- KYIV, Ukraine (AP) — President Donald Trump on Sunday claimed Ukrainian President Volodymyr Zelenskyy “hasn’t read” a U.S-authored peace proposal aimed at ending the Russia-Ukraine war.

The comments from Trump's oldest son are a sign of growing frustration over the failure of the Ukraine peace efforts to end the war

American and Ukrainian representatives continued discussions on a possible framework for a peace deal to end Russia’s full-scale invasion of its neighbor on Saturday.

Ukrainian investigators say that a criminal organization led by Zelensky’s former business partner embezzled $100 million from the country’s publicly owned nuclear power company, Energoatom. Even as Ukrainians endured blackouts caused by Russian bombing, members of the president’s inner circle skimmed money from Energoatom contracts.

The top Ukrainian negotiator said the most recent Russia peace talks in the U.S. with President Donald Trump's team were "constructive" and he will now return to Kyiv to discuss the latest proposals with President Volodymyr Zelensky.

After a number of drone sightings near European airports and military bases, mysterious aircraft were seen over Ireland as Ukraine's Zelenskyy visited.
