Pro-European integration protestors hold a rally in Independence Square, with a banner of jailed opposition leader Yulia Tymoshenko seen in the background, in central Kiev, December 12, 2013. Ukrainian protesters stood their ground after a sweep by riot police and their leaders dismissed an offer of talks from a president they say must quit for favouring ties with Russia over the European Union.
