Dozens of right-wing activists marching through Jerusalem Wednesday were filmed chanting inflammatory messages and singing provocative songs in the capital, including “Muhammad is dead,” “May your village burn,” “Death to leftists,” and “Butcher the Arabs.”

The disturbing utterances were made during the traditional “Flag Dance” on the occasion of Jerusalem Day, which drew tens of thousands of Israelis to the capital to celebrate its unification following the 1967 Six-Day War.

During Wednesday’s violent clashes, police detained at least 15 rioters, both Jewish and Arab. A focal point of tension was the Old City’s Damascus Gate, where Jewish marchers and Arab business owners hurled stones and fruit at each other. Some Jews entered the Muslim market in the area and chanted “Death to the Arabs” and “Muhammad is dead.”

More Jewish protestors were arrested nearby after yelling nationalistic chants and attempting to hurt Arabs.

Overall, two Jews and one Arab sustained light wounds as result of stone throwing during the day and received medical treatment.
