World leaders react to Russia’s attack on Ukraine: ‘A dark day for Europe’

President Biden promised that “the world will hold Russia accountable” for what he described as an “unprovoked and unjustified attack” on Ukraine.

Ukrainian President Volodymyr Zelensky said Thursday that “Russia has vilely attacked us” and that the country was “defending itself and will not give up its freedom, as they think in Moscow. For Ukrainians, their independence and right to live on their own land freely is the highest value.”
