Police have arrested 16 Croatia fans for interrupting a European Championship qualifier against Italy by throwing fireworks onto the field.
Sunday's match at the San Siro was suspended twice and the referee ordered the players off the field during the second half.
Play was halted in the first half for a few minutes and then late in the match it was stopped for 10 minutes, when there also appeared to be a small fire in the stands. Riot police waded into the stands and eventually the final 17 minutes were played.
The match finished 1-1.
Croatia coach Niko Kovac, who pleaded with fans to calm down, says, "this is not football. This is not a fair image of our country or our people."
