ATHENS, Greece (AP) — Gangs of rock-throwing youths made sporadic attacks on police stations across Athens, stoned the Interior Ministry and clashed with riot police outside Parliament on Monday in a third day of violence protesting the police shooting of a teenager.

Scattered confrontations between police and protesting youths broke out around the country today, and in Berlin and London, youths protested at Greek diplomatic missions.

Some of the worst riots Greece has seen in years began within hours of the fatal shooting of 15-year-old Alexandros Grigoropoulos in Saturday night in the often volatile central Athens district of Exarchia. Two police officers have been arrested and one is charged with murder.
