GDANSK, Poland (AP) — Croatia coach Slaven Bilic is urging UEFA to come down hard on racist soccer fans.

UEFA is looking into reports that Croatian fans threw a banana onto the field during Thursday's European Championship match against Italy and racially abused striker Mario Balotelli.

Bilic says he is "so angry with these couple of crazy supporters" because Croatia is a "modern, open-minded and tolerant state."

Bilic says authorities should "stop this kind of supporter forever."

Croatia will play Spain in its final Group C match Monday and can reach the quarterfinals with a victory.
