“We are working to gather more information regarding reports that Ukraine’s security forces disabled vehicles in a Russian military convoy inside Ukraine. We are not currently in a position to confirm these reports,” National Security Council Spokesperson Caitlin Hayden said in a statement released on the White House Web site.
She said that the U.S. authorities had warned Moscow against any attempted incursion into Ukraine without the permission and consent of Kyiv.
“We reiterate our concern about repeated Russian and Russian-supported incursions into Ukraine. Russia has no right to send vehicles, persons, or cargo of any kind into Ukraine, under any pretext, without the government of Ukraine’s permission,” she said.
