KYIV, Sept 9 (Reuters) - Swiftly advancing Ukrainian troops were approaching the main railway supplying Russian forces in the east on Friday, after the collapse of a section of Russia's front line caused the most dramatic shift in the war's momentum since its early weeks.
HELSINKI/KHARKIV, Ukraine, May 12 (Reuters) - Finland said on Thursday it would apply to join NATO "without delay", with Sweden expected to follow, as Russia's invasion of Ukraine looked set to bring about the very expansion of the Western military alliance that Vladimir Putin aimed to prevent.
The counterattack could signal a new phase in the war, with Ukraine now going on the offensive after weeks in which Russia mounted a massive assault that Ukrainian troops mostly held off.
