A Belgium protest against Israeli military action turned into an anti-Semitic rally last Sunday, after Muslim demonstrators began chanting "gas the Jews" at Jewish bystanders.
The 300 Islamic protesters, mostly young and from both the extreme left and right, were demonstrating outside an Antwerp concert hall where the Israel Defense Forces Orchestra was performing.
Sometime during the protest, a chant of "Hamas, Hamas, gas the Jews!" broke out, apparently directed at a bystander who appeared to be Jewish. Soon the entire crowd was marching down the street, chanting the hate slogan. Video of the incident was shown on national television and put online.
