Uefa is set to investigate crowd trouble that erupted during the Italy vs Croatia Group H Euro 2016 qualifying match at the San Siro on Sunday.
Flares rained down onto the pitch after Croatian midfielder Ivan Perisic equalised for the away side on the 15-minute mark.
Referee Bjorn Kuipers ordered the players off the field while Italian riot police were seen in the Croatia section to try to restore order.
Following a stoppage of around 12 minutes the match restarted and ended 1-1.
Croatia manager Niko Kovac said: "It's not the first time and it's not accidental. I hope the bodies in charge will find a way to solve the problem because it paints a bad picture of Croatia. I was ashamed and I apologised to the Italians after the game. There were families with children up there."
In 2012 Uefa fined the Croatian Football Federation (HNS) €80,000 for offences including racist abuse of the Italy striker Mario Balotelli, who was injured for last night's match.
