Chairs were hurled back and forth in Melbourne on Friday as Bosnian and Serbian fans clashed at the Australian Open in Melbourne.

The fight erupted after Novak Djokovic of Serbia defeated Bosnian-born American Amer Delic.

Two men were arrested and 30 supporters ejected from the grounds as fans threw chairs and traded punches.

It is not the first year that rival fans from different countries have clashed at the event.
