The Euro 2012 qualifier between Greece and Croatia was temporarily suspended less than three minutes after kickoff on Friday when over 100 masked individuals entered a stand and attacked the Croatia supporters.

The group, some wearing motorcycle helmets, threw flares and at least one petrol bomb in their direction. Some Croatia fans responded by ripping off seats and throwing them at their attackers.

The game resumed after a six-minute interruption, but the Croat supporters, said to number about 700, continued ripping seats and throwing them at riot police, who responded with pepper spray.

Croatia fans were involved in pre-game incidents, causing damages in the port of Piraeus, near the stadium where the game is being played.
