WASHINGTON (AP) - President Barack Obama is warning Russia there will be costs if Russia intervenes militarily in Ukraine.
Obama says the U.S. is deeply concerned by reports of military movements by Russia inside Ukraine.
He says any violation of Ukraine's sovereignty and territorial integrity would be destabilizing. He says it would violate Russia's commitment to respect Ukraine's borders and would invite global condemnation.
Obama says the U.S. stands with the world community to affirm there will be costs for an intervention.
Obama spoke at the White House late Friday.
