President Barack Obama on Friday expressed concern about reported Russian military movement inside crisis-torn Ukraine and warned of consequences.
"We are now deeply concerned by reports of military movements taken by the Russian Federation inside of Ukraine," he told reporters at the White House.
"Any violation of Ukraine’s sovereignty and territorial integrity would be deeply destabilizing," he said in a brief appearance. "The United States will stand with the international community in affirming that there will be costs for any military intervention in Ukraine."
