Barcelona is on fire: the youth protest turned into riots. Riots broke out in central Barcelona during a youth protest, El Mundo reports. Protesters gathered in Plaza Catalunya - many wearing black clothes and hoods. The protesters set trash cans on fire, knocked down motorcycles, set up and set fire to a barricade. The wave reached the embankment: there protesters smashed the windows of the bus stops and broke traffic lights. The police had to use special measures to control the crowd. According to Politico, the protest wave is covering more and more countries in the European Union - from France and Italy to the Czech Republic and Albania.
