Thousands of demonstrators filled the streets of Greece’s two largest cities on Nov. 17 to commemorate the 49th anniversary of the uprising in which two dozen students were killed by the military junta at Polytechnic University in Athens. Heavy clashes went on through the night of the memorial protests, with youth using fireworks, homemade bombs, rocks, and other projectiles against riot police who shot a large water cannon and copious amounts of tear gas.
