ATHENS, Greece (AP) — About 16,000 people marched to the U.S. Embassy in Athens under tight police security on Tuesday to commemorate a student uprising that was crushed by Greece's military regime in 1973.
Police said about 8,000 people were walking from the Polytechnic building in central Athens, in a march that has been marred in previous years by violence from far-left protesters. Up to 5,000 police were on duty to preserve the peace.
Another 8,000 people were taking part in a separate march organized by the Communist Party from another part of the city center to the embassy.
Many Greeks blame Washington for backing the dictatorship that ruled Greece from 1967-74.
Earlier Tuesday, leftists heckled left-wing Prime Minister Alexis Tsipras when he laid a wreath at the Polytechnic, where most of the students killed by security forces in the uprising died.
