DEMONSTRATORS caused serious damage to the central offices of newspaper Apogevmatini and torched several parked cars last week after breaking off from a rally protesting a hand grenade attack on a left-wing human rights group and immigrant support network in Exarchia. Demonstrators used sledgehammers, iron bars, sticks and stones to smash up the facade and torch several parked cars. Police fired tear gas and threw stun grenades to disperse the vandals. Although they returned later, using sticks and rocks to attack riot police.
