Russian and Ukrainian troops in Crimea are involved in a tense stand-off...Moscow forces have wrested control of Ukraine's Crimea -- a region with an ethnic Russian majority. At a UN Security Council meeting, Russia says its troops went into the Ukrainian region upon a request by the ousted president, Viktor Yanukovich. (SOUNDBITE) (English) VITALY CHURKIN, RUSSIAN AMBASSADOR TO THE UNITED NATIONS, SAYING: "I think it's important to realise that the person who we believe is legally president of Ukraine also shares our concerns of large segments of the Ukrainian population about what is going on and is appealing to Russia to use our armed forces to change the situation and to prevent the situation from further deteriorating." The Russian UN envoy showed reporters a copy of the letter Yanukovich allegedly wrote to Russian President Vladimir Putin on Saturday. His statement comes as two Russian warships were spotted passing through Turkey's Bosphorus on the way to the Black Sea port of Sevastopol. Putin's show of force comes after Ukraine's new leadership began a course towards the European Union and away from Moscow's influence after generations of Soviet Communist rule. The crisis over Crimea, is causing outrage in the West. U.S. Secretary of State John Kerry makes his way to Kiev to meet the country's new leaders and show support for its sovereignty. The United States has announced a suspension of all military engagements with Russia, including military exercises and port visits, and freezing trade and investment talks. President Barack Obama has also been holding high level meetings at the White House with his national security advisers to discuss what else it could do to "isolate" Russia.
