At NYT, "Anti-Austerity Protest in Greece Turns Violent":
ATHENS — Thousands of Greeks took to the streets of the capital on Wednesday for a protest against a fresh wave of austerity measures which was marred by violence as a general strike brought international travel and public services to a standstill.
The walkout — Greece’s seventh general strike this year — grounded flights, kept ferries in ports, halted train services and shut down government offices and schools while leaving hospitals to operate on emergency staffing and causing a news blackout as journalists joined the action. Public transport was operating for most of the day to enable Athenians to attend demonstrations in the city center.
Around 20,000 people answered the call of unions representing civil servants, private sector workers and the Communist Party for three separate demonstrations. The rallies were mostly peaceful until the early afternoon, when self-styled anarchists broke off from the crowd and attacked the police with firebombs and chunks of stone torn up from sidewalks.
