The rioting began in Athens late on Saturday soon after the shooting in the central Exarchia district, where youths threw petrol bombs at police, burnt dozens of cars and smashed shop windows. It quickly spread to Greece's second largest city of Thessaloniki and other towns in northern Greece. Cities on the holiday islands of Crete and Corfu also saw protests at the shooting, which prompted Interior Minister Prokopis Pavlopoulos to offer his resignation. Prime Minister Costas Karamanlis, whose fragile government has been rocked by a series of scandals, rejected it, a ministry spokeswoman said.
