Two separate groups, totaling over 150 youths, went on the rampage in Athens and Thessaloniki late Saturday night and early Sunday morning, damaging several vehicles and bank cash machines before being dispersed by riot police, who arrested one student.

A mob of some 30 anarchists started throwing Molotov cocktails into garbage bins around Exarchia Square in central Athens just before 10 p.m. on Saturday, damaging five parked cars with sticks and stones. Another 20 youths rioted in the same area shortly after 1 a.m. on Sunday morning but no damage or arrests were reported.

In Thessaloniki, more than 100 anarchists went on the rampage after a concert at the city’s university, throwing firebombs at a number of nearby cars and ATMs. Riot police used tear gas to disperse the mob before arresting a 22-year-old student for his alleged part in the riot.
