Anti-Israel activists calling for an intifada and an end to the Jewish state prevented the mayor of Jerusalem from addressing students in California.

Members of Students for Justice in Palestine marched into a hall on Wednesday where Jerusalem Mayor Nir Barkat had just begun to address students at San Francisco State University on a topic related to high-tech. They screamed anti-Israel slogans calling for an intifada and to replace Israel with “Palestine.”

The anarchists drowned out the mayor’s speech, forcing it to end abruptly.
