Ukraine reported clashes with Russian troops on Sunday on fronts in the east and south, with six civilians killed in one rocket attack, as the United States sought to marshal international support in opposing Russia's invasion.
Russian forces attacked Ukrainian positions near the eastern town of Sloviansk but were forced to withdraw, Ukraine's military said, adding that Russian forces had launched a cruise missile attack on the northeastern city of Kharkiv from their side of the border. It gave no details of damage or casualties.
