President Obama has ramped up pressure on Russia to de-escalate the growing tensions in Ukraine by signing an executive order that imposes visa restrictions and other sanctions against Moscow. On Thursday the president also denounced a referendum by the Crimean parliament to break away from Ukraine to join the Russian Federation calling the move a violation of international law. The Crimea region has been at the center of a tense power struggle between the new Ukrainian government and Russian President Vladamir Putin since the fall of former Ukrainian President Viktor Yanukovych last month.
