UKRAINE-UNREST-POLITICS-EU-RUSSIA

Riot police stand guard as they surround Independence Square in Kiev on December 20, 2013, where the Ukrainian opposition is camped out. Ukrainian President Viktor Yanukovych told the West on December 19 to stay out of his country's political crisis, after top European and US diplomats visited the protests that have raged for a month in central Kiev. The Ukrainian government last month unexpectedly halted work on key political and free trade agreements with the European Union, sparking the largest demonstrations since the pro-democracy Orange Revolution in 2004.
