The US will back Ukraine in its fight against Russia for "as long as it takes", US President Joe Biden has said on an unannounced visit to Kyiv.
"We have every confidence you're going to continue to prevail," he said.
Mr Biden's first trip to Ukraine as president came days before the first anniversary of Russia's invasion.
He said that Russia's President Vladimir Putin had been "dead wrong" to think Russia could outlast Ukraine and its Western allies.
He met Ukrainian President Volodymyr Zelensky and the pair visited a memorial to soldiers who have died in the nine years since Russia annexed Crimea and its proxy forces captured parts of the eastern Donbas region.
Mr Biden's presence was intended to reaffirm America's "unwavering commitment to Ukraine's democracy, sovereignty, and territorial integrity", according to a White House statement. 1688บาคาร่า
