ATHENS - YOUTHS protested outside of Athens' main police headquarters on Monday, pelting riot police with flour to protest the shooting death of a teenager. Riot police responded with small amounts of tear gas.

Some 2,000 youths at the rally blocked one of the capital's main avenues, chanted slogans and occasionally threw oranges and plastic water bottles at riot police guarding the building. Police did not respond until a group threw flour at them, then fired some tear gas that briefly scattered the demonstrators.

Earlier, about 50 youths shouted slogans outside the capital's main court complex, where five people arrested during last week's riots were to appear before an examining magistrate. Riot police guarded the complex and no disturbances were reported.

Police said no violence was reported in Athens overnight after an uneventful day Sunday.

Greece has seen its worst riots in decades after 15-year-old Alexandros Grigoropoulos die Dec 6 in a police shooting. The riots quickly spread from Athens to more than a dozen cities.

For a week, youths smashed and burned stores and cars, and hurled petrol bombs and rocks at riot police, who responded with stun grenades and large amounts of tear gas.

Dozens of people were injured in the rioting, while hundreds of stores were damaged or looted and more than 200 people were arrested. The policeman accused of killing the teenager has been charged with murder and is being held pending trial.

Greek youths protesting since the boy's death are angry not just at the police but at an increasingly unpopular conservative government and over economic issues.

Some groups, mostly left-wing students, have vowed to keep up the protests until their concerns are addressed. Groups have called for riot police to be pulled off the streets, for police to be disarmed and for their concerns over social inequality to be heard. -- AP
