Russia vowed to continue its bloody offensive in Ukraine as the war neared its seventh week Wednesday, as President Vladimir Putin insisted the campaign was going as planned despite a major withdrawal and significant losses.
Thwarted in their push toward the capital, Kyiv, Russian troops focused on the eastern region of Donbas, where Ukraine said 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.
