KYIV (Reuters) -U.S. President Joe Biden made an unannounced visit to Ukraine on Monday, a major show of support ahead of the one-year anniversary of Russia's invasion which has seen Moscow launch a massive assault across frontlines in the east.

Air raid sirens blared across the Ukrainian capital as Biden visited Kyiv, but there were no reports of Russian missile or air strikes.
