A man sweeps the floor next to a poster of Venezuela’s President Nicolas Maduro, with the word “dictator” written over it, at the Altamira Square in Caracas February 25, 2014. Anti-government demonstrators put up barricades and set fire to trash in Caracas on Monday despite calls from within the opposition to rein in protests that have led to 13 deaths in Venezuela’s worst unrest for a decade.
