In this video, thousands of people in Bosnia march outside a hotel where the Israeli national soccer team is staying, displaying terrible anti-Semitic hatred.

As part of a EuroCup soccer qualifying match, Israel faced off against Bosnia, exposing a shocking presence of raw anti-Israel sentiment. Though the hatred is directed at Israel, it isn’t much of a stretch to understand that this is plain anti-Semitism.

What else could cause the Bosnian people to be so upset and extreme in their march? What do chants about Palestine have to do with a soccer game?
