Anti-Semitic incidents in the United States up more than 60%.

Anti-Semitic incidents in the United States up more than 60%. (INN).

Anti-Semitic incidents on American college campuses nearly doubled in 2015, the Anti-Defamation League (ADL) reported in an audit released on Wednesday, according to JTA.

In addition, the number of anti-Semitic assaults across the country increased by more than 60 percent last year, the organization's audit found.

A total of 90 incidents were reported on 60 college campuses last year, compared with 47 incidents on 43 campuses in 2014. Campus anti-Semitic incidents accounted for 10 percent of the total.

In one incident in January, swastikas were spray-painted on the exterior wall of a Jewish fraternity at the University of California, Davis, on the 70th anniversary of the liberation of Auschwitz from the Nazis.

The ADL audit recorded a total of 941 anti-Semitic incidents in the United States in 2015, an increase of three percent from 2014.

56 of the incidents were assaults, the most violent category recorded in the audit, up from the 36 reported the year before.

These assaults included attacks on visibly Jewish men as they returned home from synagogue in New York and Florida, and a kippah-wearing high school student in Denver who was struck with a rock by an assailant who also called him "Jewboy" and "kike."

The ADL audit is the latest confirmation of the rising numbers of anti-Semitic incidents around the world and specifically in the United States, which has not been immune from the phenomenon.

“We are disturbed that violent anti-Semitic incidents are rising,” Jonathan Greenblatt, ADL's CEO, said in a statement about the audit quoted by JTA. “And we know that for every incident reported, there’s likely another that goes unreported. So even as the total incidents have remained statistically steady from year to year, the trend toward anti-Semitic violence is very concerning.” Read the full story here.
