CNN -From Journalist Anthee Carassava
ATHENS, Greece (CNN) -- The Greek government has appealed for calm after rioting returned to cities Sunday, following a night of violence during which youths battled police across the country.
Demonstrators barricaded city streets Sunday in Athens and Thessaloniki and hurled petrol bombs as they battled with police, who fought back with tear gas in the second day of rioting. Rampaging youths smashed storefronts and burned businesses, leaving shattered glass and burnt debris scattered across both cities. Government officials, fearing more violence, swiftly condemned the shooting. "An investigation is underway and those found responsible with be punished," said Interior Minister Prokopis Pavlopoulos, who earlier had his resignation refused by prime minister Kostas Karamanlis. "Measures will also be taken to avoid such incidents again in the future." "It's still very tense," journalist Anthee Carassava told CNN from Athens. "You can almost cut it with a knife. The scenes in downtown Athens have been harrowing."
