Putin vows to press invasion until Russia’s goals are met

Vladimir Putin vowed Tuesday that Russia’s bloody offensive in Ukraine would continue until its goals are fulfilled and insisted the campaign was going as planned, despite a major withdrawal in the face of stiff Ukrainian opposition and significant losses.

Russian troops, thwarted in their push toward Ukraine’s capital, are now focusing on the eastern Donbas region, where Ukraine said Tuesday it was investigating a claim that a poisonous substance had been dropped on its troops. It was not clear what the substance might be, but Western officials warned that any use of chemical weapons by Russia would be a serious escalation of the already devastating war.
