Russia pounded areas in Ukraine’s east, including the last pocket of resistance in besieged Mariupol, as the war pushed Finland closer to seeking NATO membership. The conflict on the ground slogged on Thursday even as the globe-shaking repercussions of the invasion spread. Ukraine’s military recaptured some towns and villages in the country’s northeast but acknowledged that Russian forces have seen “partial success” farther south in the eastern industrial heartland of the Donbas. Finland’s president and prime minister said Thursday that the Nordic country should apply “without delay” for membership in the Western alliance.
