Italian security chief Roberto Massucci blamed Serbian authorities for allowing unruly fans to travel to the Euro 2012 qualifier in Genoa.
The match between Serbia and Italy was abandoned after just six minutes played due to crowd disturbances at the Luigi Ferraris stadium.
Serbia goalkeeper Vladimir Stojkovic was attacked by his own fans prior to the game and was later taken to hospital, while crowd trouble erupted inside the ground as Serbian fans hurled flares, cut through protective nets and smashed perspex barriers.
''Fans that are so dangerous should not have arrived in Genoa,'' said Massucci. ''They should have been stopped by the Serbian officials. We were aware that this game had a risk factor but a behaviour of such aggressiveness we had not experienced for some time.
''From the traditional channels of communication with the Serbian police, we had not been given any signs of the degree of danger of these fans. We, through experience, had arranged an adequate security, but we would have never imagined such a high level of aggressiveness. But there was no-one here from the Serbian police.''
Long before the game, Italian police clashed with Serbian fans near the hotel where their team was staying.
The game was then delayed by 35 minutes due to crowd disturbances after Serbian fans threw flares in the direction of the north stand where Italian supporters were seated, and onto the pitch. When the game finally started, more flares and fireworks were thrown onto the pitch forcing Scottish referee Craig Thomson to stop the match.
''It's a difficult time for everyone,'' said Italian Football Federation general director Antonello Valentini. ''We apologise to our fans. The police and us, as a federation, did what we could do in order for the game to be played.
''The referee took the decision to abandon the game after the second flare was thrown onto the pitch and told us he could not guarantee the safety of the players.''
Italy coach Cesare Prandelli could not hide his disappointment after the game.
''We are extremely sad and very bitter,'' he said. ''There were so many children that wanted to watch a show and were not able to do so. I've never experienced anything like this.
''The (Serbian) players have been assaulted by their own fans in their bus. Their goalkeeper (Vladimir Stojkovic) was in our changing room, he was trembling and had fear not only about tonight but also in view of returning home.
''The ultra fans seemed organised. It appeared as though they would have done everything possible to make sure the game was not played. According to the Serbian players, that was their aim.''
UEFA will now wait for report as they look to investigate the incidents in Genoa. A statement from UEFA read: ''UEFA now awaits the receipt of the official UEFA delegate's match report before deciding whether to open a disciplinary case.''
