Anti-Semitic graffiti was recently found painted on the exterior of a Los Angeles synagogue.

Police are investigating who wrote “f**king Jews” on the Mishkan Torah religious seminary and synagogue in the neighbourhood of Tarzana on Tuesday, but have no suspects in custody, CBS’s KCAL9 television channel reported.

“It’s really hurtful, I mean to all the members here, they’re being hurt with such a thing that somebody passed by a synagogue and wrote such a thing on the wall,” Rabbi Shlomo Haghighi, who works at the synagogue, told KCAL9.

Hate crimes against Jews in America rose by more than a third in 2017 and accounted for 58 per cent of all religion-based hate crimes, according to data released in November by the FBI. The report noted a 23 per cent increase in religion-based hate crimes in 2017 to 1,564, representing about 20 percent of all hate crimes.
