“While anti-Semitism continues to rear its head in the United States and throughout the world, we must move from defense to offense,” said Ambassador Danon.

Thousands of marchers assembled in Manhattan Sunday morning, taking to the streets and flooding the Brooklyn Bridge for hours as they crossed into the borough of Brooklyn amid chants of “No Hate, No Fear,” the theme of the assembly in the works for days now.

An estimated 25,000 people converged on Manhattan’s Foley Square and made their way to Brooklyn’s Cadman Plaza, where they heard from community leaders and organizations that urged Jewish pride and unity in the face of escalating anti-Semitism. Sponsors included the Jewish Community Relations Council of New York, the Anti-Defamation League, the Board of Rabbis of New York, the American Jewish Committee and the UJA-Federation of New York.

To mark the occasion, Israel’s U.N. Ambassador Danny Danon declared that “the huge show of solidarity in NY is conveying a clear message to the entire world that it is time for action and not just talk.”

“While anti-Semitism continues to rear its head in the United States and throughout the world, we must move from defense to offense. We will not be silenced when Jews are murdered in synagogues and will not be ignored when those who wear kippahs are being killed in the street. We must join hands and stand as a wall against the wave of hatred.”

Ambassador Danon added that “this is the time for legislation, the time for enforcement, and the time for determined action against the wave of hatred that sweeps across social networks. In combating anti-Semitism, we expect every country to adopt determined and effective legislation and clear condemnation from the U.N. and the international community.”
