Riot police
At least 300,000 under the banner of "People of Europe: Rise Up!" gathered in the centre of Rome, according to the organizers. During the peaceful march against corporate greed and austerity measures, a group of people broke away from the main demonstration and threw rocks, bottles and incendiary devices at banks and riot police. Riot police charged and clashed with the protesters repeatedly, firing water cannons and tear gas. At least 135 people were injured, including 105 police officers. 12 people were arrested.
