Obama Warns Russia Not to Intervene in Crimea

WASHINGTON — As Ukrainian leaders accused Russia of carrying out an armed invasion in the Crimea region, President Obama on Friday warned Russia not to intervene militarily, saying the United States would stand with the world to condemn a violation of Ukraine’s sovereignty. “There will be costs,” Mr. Obama declared in a brief statement from the White House. He said the United States government was “deeply concerned” by “reports of military movements taken by the Russian Federation inside Ukraine.” He said any intervention militarily in Ukraine would be “deeply destabilizing” and would represent a “profound interference” in the Ukrainian people’s right to determine their own future.
