Here we see a protest which pitted Serbs against Bosnians at the Australian Open tennis in Melbourne in January. The protests culminated in chair-throwing and scuffles.
Unlike with the Israeli Shahar Peer, there has been no case of players of former Yugoslav ethnicity being denied visas due to "security fears" to play in tennis tournaments since the Melbourne violence. Nor have there been any arrangements, as in Sweden, to play tennis matches involving former Yugoslavs in empty arenas. Very odd.
