WASHINGTON (Reuters) - Ukrainian Defense Minister Oleksii Reznikov called for global unity to prevent a new Russian "escalation" against Ukraine during a visit to the Pentagon on Thursday, as Kiev and Washington warn of what they say is unusual Russian military activity.
The U.S. military has so far stopped short of describing Russia's buildup as a preparation for attack. On Wednesday, U.S. Defense Secretary Lloyd Austin conceded that "we're not sure exactly what Mr. Putin is up to."
