An anti-government protester holds a Ukranian flag as he advances through burning barricades in Kiev’s Independence Square February 20, 2014. Ukrainian protesters hurling petrol bombs and paving stones drove riot police from the central square in Kiev on Thursday despite a “truce” which embattled Ukrainian President Viktor Yanukovich said he had agreed with opposition leaders.
