An arson attack took place in the unpopular gold mines of Skourias, near Thessaloniki (Macedonia, Greece), which are accused of heavy pollution and health damage. Some 40 people set in fire some of the facilities but exact extent of the damage is not known. Several anti-mine activists have been arrested but there seems to be no evidence against them, so it is just arbitrary repression. While some of them have been already set free the spat of arbitrary arrests continues in the district as of now. No formal accusations have been pushed against any of them.
