According to a report from the Jerusalem Post, a video was released showing the fans joining a protest in support of Palestinians in Vienna's central St. Stephen's square.
The fans were in town for a friendly soccer match between Bosnia and Austria, which resulted in a one-all draw.
Initially, the protest was peaceful, with cries of "Free Palestine." Within minutes, however, the protest descended into hate speech, with shouts of "Ubij, ubij Židove" ("Kill, kill the Jews!")
Neither Bosnian nor Austrian officials have issued a statement condemning the incident.
According to Der Standard newspaper, police have begun an investigation into the incident. Spokesperson Roman Hahslinger said approximately 100 people participated in the rally, half of whom were Bosnian soccer fans.
