Pro-russian demonstrators demonstrate in front of the Crimean parliament building in Simferopol on February 27, 2014. Ukraine's ousted pro-Moscow president Viktor Yanukovych emerged defiant on February 27 from five days in hiding as the country's new leaders issued a blunt warning to Russia against any aggression on the volatile Crimean peninsula.
