Levski Sofia fans watch the UEFA Europa League group C football match against Lille in Sofia, 2010. Bulgaria and Bosnia's prime ministers urged football fans to refrain from violence ahead of a tense UEFA Europa League game between Levski and Sarajevo in the Bosnian capital on Thursday.

Bulgaria and Bosnia's prime ministers urged football fans to refrain from violence ahead of a tense UEFA Europa League game between Levski and Sarajevo in the Bosnian capital on Thursday.

"We are true fans also and we urge our friends at the stadium in Sarajevo: Do not ruin the game! Leave the rivalry to the players and do not insult or humiliate the other fans," Boyko Borisov and Vjekoslav Bevanda said in a joint statement Wednesday.

Sarajevo and Levski will face each other Thursday in a second leg match of the Europa League's second qualifying round.

The Bulgarian team won the first leg 1-0 last Thursday in Sofia but the match was marred by provocative chants from the Bulgarian crowd that sparked angry calls for revenge among the Bosnian fans.

Bulgarian media said Sarajevo had filed an official complaint with UEFA.
