KYIV (Reuters) - Ukrainian President Volodymyr Zelenskiy said on Saturday it was "a crucial moment" to decide on Ukraine's membership of the European Union, as Russia continued to invade its neighbour.

       Zelenskiy said in a tweet he had discussed with European Council President Charles Michel "further effective assistance and the heroic struggle of Ukrainians for their free future."
