Alexander Zaldostanov (C), nicknamed "the Surgeon", leader of a group of Russian bikers called the Night Wolves, attends a rally of pro-Russian activists waving the Russian flag, in front of the local parliament building on February 28, 2014 in Simferopol, Crimea, Ukraine's strategic peninsula. Pro-Russian activists flexed their muscles in in Crimea on Friday, swarming government buildings after Kalashnikov-toting men in fatigues descended on two key airports, as tensions mounted over the strategic Ukrainian peninsula. Hundreds of pro-Moscow protesters in Crimea's capital Simferopol massed outside the regional parliament, seized on February 27, 2014 by separatist commandos, as 50 others formed a barricade outside the Ukrainian presidency's local office, blocking its newly designated director from going inside.
