In the Ukrainian province of Crimea, Russian supporters seized a government building today. Russia will grant protection to ousted President Viktor Yanukovych and Russian troops are conducting exercises on the Ukrainian border. After a meeting of NATO ministers in Brussels today, US Defense Secretary Hagel issued a warning. "I expect Russia to be transparent about these activities, and I urge them not to take any steps that could be misinterpreted, or lead to miscalculation during a … time with great tension."
