Authorities in Greece have detained 313 people after a raid on the university campus in Thessaloniki. Riot police were attacked by mobs hurling over 100 Molotov cocktails early Saturday. Greek police said groups wearing hoods emerged from the Aristotle University campus to attack the police. All those detained were released without charges. Such attacks near the campus are not uncommon, but this is the first time so many people were detained. Riot police used tear gas and stun grenades to disperse the attackers. One officer and a civilian were injured. An investigation is underway.
