Tensions between the Ukraine and Russia have escalated to a new fever pitch. Ukraine has announced that it will mobilize its military reserves and has called on them to report to their stations immediately. Ukrainian Prime Minister Arseniy Yatsenyuk said "This is actually a declaration of war to my country." On Saturday, Russian President Vladimir Putin was granted authority by his government to send troops into the Ukraine. On Sunday, hundreds of Russian reportedly surrounded the Ukrainian military base at Perevalne on the Crimea peninsula. Others are reportedly digging trenches at the narrow land crossing between Crimea and rest of Ukraine.
