Yiannis Boutaris, 75, was kicked in the head and legs and beaten with bottles by a group of nationalists angry over his appearance at a remembrance event.

The mayor, who is known for his anti-nationalist views, was attending a ceremony to mark the killing of ethnic Greeks by Turks in World War One.

Politicians have condemned the attack.
