The disturbing video of a man beaten in Times Square is among the recent attacks against Jewish New Yorkers caught on camera – from violent assaults to harassment, like an incident in Brooklyn where police say two teens accosted several victims outside of a synagogue.

While police have been able to make a number of arrests, Jewish leaders say it's part of a troubling national trend in the wake of the conflict between Israel and Hamas.

"We've seen an uptick of anti-Semitism, upwards of 70% of anti-Semitism right here in New York," said Elana Broitman, senior vice president of public affairs for Jewish Federations of North America. "We know we've seen violent attacks. We've seen desecration."

JFNA is one of the groups behind a virtual rally and day of action against anti-Semitism.

"We were so grateful for the civil rights leaders and the interfaith leaders including an imam from New York, Cardinal Dolan, and others stand together and speak out against anti-Semitism," said Broitman.

The virtual gathering also demanded more congressional funding for security to protect non-profit organizations and to address hate crimes and other programs. This, as Mayor Bill de Blasio announced a $3 million initiative to fight hate crimes in the city, citing the recent anti-Semitic attacks here.

"I spoke to two of the victims of those attacks,” said the Mayor. “I heard the fear they felt, the pain they felt, the sense of insecurity - we can't let that happen in New York City, and the NYPD is going to play a crucial role.”

Mayor de Blasio has also promised more police presence in Jewish neighborhoods starting this Friday for the holiday weekend, joining the effort to ease fears and show solidarity against hate.
