U krainian President Volodymyr Zelenskyy on Wednesday said he told President Donald Trump and European leaders that Russia's Vladimir Putin is "bluffing" on pursuing peace as preparations for Friday's U.S.-Russia summit in Alaska continue.

Ukrainian and European leaders pursued last-ditch efforts on Wednesday to persuade U.S. President Donald Trump not to strike a Ukraine peace deal with Russia's Vladimir Putin, which they fear could sell out Kyiv's interests.

"We talked about a ceasefire today. President Trump said this is one of his priorities in conversation with President Putin," President Volodymyr Zelensky said.
