Pro-European integration protesters sing the Ukrainian national anthem during a mass rally at Independence Square in Kiev December 15, 2013. Thousands of Ukrainian massed on Sunday for a rally against President Viktor Yanukovich just days before he heads for a meeting in the Kremlin which the opposition fears will slam the door on integration with the European mainstream. The street protests erupted after the November 21 decision by Yanukovich to walk away from a trade-and-political agreement with the EU after years of careful preparation and turn to Moscow, Kiev's old Soviet master, for aid to save Ukraine's distressed economy.
