ATHENS, GREECE - APRIL 1:  Protesters clash with riot police blocking the way to the parliament on April 1, 2014 in Athens, Greece. Authorities banned all protests in a large section of central Athens for the Eurogroup and a later meeting of all European Union finance ministers. Nevertheless, some 7,500 anti-austerity demonstrators held three separate protests outside the exclusion zone, and some tried to break through a riot police cordon blocking their way to Parliament.
