The incidents were the first of their sort under the new SYRIZA government, and certainly took authorities by surprise (as well as those within the SYRIZA party who have never hidden their fondness to these vigilantes as well as to what they once described as repressive police tactics).
During the clashes, the Greek riot police did not intervene and despite of this they were still flooded with firebombs, rocks and slabs of cement from the rioting youths.
Earlier, following a march through central Athens, along with far-left ANTARSYA (Anticapitalist Left Cooperation for the Overthrow)party, which did not join in the rioting, the anarchists targeted jewelry and bank storefronts and bus stops.
Editor's Note - Time for SYRIZA to clean up house... and forget about having a riot police force that passes out flowers instead of calming down rioting vigilantes and hooligans.
