(CNN) -- Serious crowd trouble has led to Tuesday's soccer match between Italy and Serbia in Genoa being abandoned after just six minutes.
Disturbances in the area of the Marassi stadium where visiting Serbian fans were congregated meant the kick-off had to be delayed by more than 30 minutes.
And, when play began, referee Craig Thomson stopped the match after flares were thrown from the same end as the earlier disturbances, with one appearing to strike Italian goalkeeper Emiliano Viviano.
Following consultations between European football's governing body UEFA, Italian and Serbian officials, the players left the pitch, without returning.
Italy coach Cesare Prandelli told reporters: "We're not playing this game. I have never seen anything like this before."
Before kick-off, three Serb fans climbed onto a security screen and initially refused to get down, while police, firefighters and stewards surrounded the visiting fans as flares and objects were hurled at the Italian fans.
The match was a Group C qualifier for the Euro 2012 championships.
