The Athens protest march marking the zenith of the general strike called for the 5th of May was attended by an approximate 200,000 (20,000 which is the foreign broadcast number referring to the PAME march alone), although because of lack of media coverage due to the media participation in the general strike no concrete estimates can be made. After the PAME (Communist Party union) protesters left Syntagma square, the first lines of the main march started arriving before the Parliament with the first clashes erupting at the end of Stadiou street. The march then walked on the Unknown Soldier grounds leading the Presidential Guard to retreat, and attempted to storm the Parliament but was pushed back by riot police forces which today demonstrated a particularly staunch attitude and resolve against the demonstrators. Soon battles erupted around the Parliament with protesters throwing Molotov cocktails and rocks, with one riot police armored van torched, and the police responding by extended use of tear gas that soon made Athens’ atmosphere unbearably acrid. As more blocks reached Syntagma square, the battles spread across the city center and lasted for more than five hours.War-Zone Athens: three people dead, many buildings burning as general strike march turns into a battle.
