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.

The meeting will be the first time in four years that a U.S. president has met with Putin since the Russia-Ukraine war began.
