Rallies were held in dozens of cities on Saturday under the banner of “Global Noise,” a worldwide day of protest against austerity and inequality. Organizers called on demonstrators to create a global “casserole march,” inspired by protests featuring the banging of pots and pans by the Indignados in Spain and the “Red Square” student movement in Quebec. In Madrid, thousands of people marked “Global Noise” with a march to the headquarters of the European Union, just one day after it was awarded the Nobel Peace Prize.
