Greek riot police fired tear gas into crowds of protesting students and teachers, who pelted them with rocks and chunks of marble in front of parliament in the seventh day of civil unrest, reported dpa.
Waving black and red anarchist flags, hundreds of students, made their way up the steps to parliament to the Tomb of the Unknown Soldier before riot police pushed them back.
Protestors also reportedly entered the main branch of the National Bank of Greece in the capital sending employees running in panic.
The riots, which have spread to all corners of the country, are the worst in decades, destroying hundreds of shops, banks, buildings and cars in more than eight cities across Greece, including Athens and the port cities of Thessaloniki and Patras.
The violence was triggered by the police shooting of a 15-year-old boy last weekend. dpa cp wjh
