Unrest returned to the streets of the capital on Saturday when dozens of self-styled anarchists clashed with riot police during an anti-government protest. According to police, about 150 hooded youths broke away from the main body of the march, comprising about 1,000 people, and started throwing rocks and other objects at police. Riot officers responded by firing tear gas and detained three people for questioning. There were no reports of injuries. The rioters, demanding the release of those arrested during last month’s ferocious riots, torched a newspaper kiosk and a bus station and smashed several storefronts. They then proceeded to Exarchia, the district where a teenager was killed by a a police bullet last month, where they set fire to several trash cans and a car and smashed up sidewalks. A similar march took place in the western city of Patras, causing damage to a newspaper office and other buildings. In Thessaloniki late on Saturday, self-styled anarchists firebombed a riot police van parked outside state television offices. There were no injuries or arrests.
