In Agoura Hills, an electronic road construction sign was hacked to say “Gas the Jews.”

In Sherman Oaks, a supermarket customer watched as a man pushed a woman, saying “out of my way, Jewish bitch” followed by chants of “Heil,” “Trump” and “9-11 was the Jews’ fault.”

Elsewhere in Los Angeles, a suspect approached a man and called him a “f*****g Jew” before beating him.

These were among the 211 anti-Semitic incidents reported in California last year, up 21 percent over the prior year, according to the Anti-Defamation League’s annual Audit of Anti-Semitic Incidents released Monday.

Nationwide, there was an increase of 34 percent of anti-Semitic incidents to 1,266 reported last year.

Perhaps most troubling is that early numbers show that anti-Semitic incidents across the nation spiked 86 percent in the first quarter of 2017 compared to the same period in 2016.

These include some 160 bomb threats at Jewish institutions, including the Westside Jewish Community Center in Los Angeles, according to the ADL.

While reported anti-Semitic assaults decreased nationally last year by about 36 percent, incidents in California included six reported assaults – three of those in the Los Angeles area – up from one in 2015, according to the ADL.

In addition to the particularly concerning increase in assaults in the state, “we also continue to see reports of what we call ‘old-fashioned anti-Semitism – heinous remarks about Jews – both verbally and in writing,” Amanda Susskind, ADL Pacific Southwest regional director, said in a statement.

Last year, there was “a large number” of swastikas reported on Jewish-owned vehicles in communities such as North Hills, Woodland Hills, Westwood and Santa Monica, she said.

Anti-Semitic vandalism in California increased about 12 percent last year, while nationwide it increased 35 percent, according to the ADL audit.
