Paris authorities on Wednesday banned a Gaza solidarity demonstration due to concern for the public’s safety after a similar event last week devolved into an anti-Semitic riot.

The rally, which was set to take place on Saturday, was outlawed “due to grave risks to public order in a context of aggravated tension,” according to police sources.

The insiders referred to the event last week in which two synagogues in Paris were attacked following a hate-filled protest in the city’s Bastille Square, where a crowd of over 7,000 people called for attacks on Jewish targets, screaming “death to the Jews” and “Hitler was right.”

Jewish human rights group the Simon Wiesenthal Center on Wednesday thanked French Prime Minister Manuel Valls for barring the planned event.

“Such a mob marching on a Shabbat and baying for Jewish blood, would have  undoubtedly gone after synagogues filled with Jewish worshipers,” said SWC France President Richard Odier and Shimon Samuels, the Center’s Director for International Relations.
