“Thousands of Greeks marched behind a blood-stained national flag on Saturday to commemorate the violent suppression of a 1973 student uprising against a US-backed military junta. The bloodied flag that flew over the Athens Polytechnic on the night of November 17, 1973 — seen as a key moment in the restoration of democracy to Greece — was carried as usual at the head of the annual demonstration in memory of those who died. Police said about 20,000 people marched in total in the capital. Outside the U.S. embassy, some of the protesters set fire to an American flag.”
