Ukrainian President Volodymyr Zelenskiy paid tribute on Monday to U.S. nationals who have fought in the 15-month-old war against Russian invaders, saying they were devoted to upholding the values of freedom.
"We Ukrainians will always be grateful to the U.S. and every American for extraordinary support," Zelenskiy, standing outside his office in Kyiv, said in English in a video message marking the U.S. Memorial Day holiday.
