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's statement comes as his administration is expressing growing concern over Russian intentions in Ukraine. Secretary of State John Kerry delivered a blunt warning Friday to Moscow against military moves in the country's southern Crimea region that could further inflame tensions.
Ukraine's acting President Oleksandr Turchynov has urged Russian President Vladimir Putin to stop "provocations" in Crimea and pull back military forces from the peninsula.
Turchynov stepped in as president after Viktor Yanukovych fled Kiev last weekend.
