The most common category of incident was insults shouted or spoken on the street, accounting for 19 percent of the total, or 24 incidents. Online anti-Semitic harassment in the form of emails and electronic messages totalled at 12 cases.One of the cases featuring violence was reported this year in Amsterdam by a non-Jewish woman of Moroccan descent who is married to a Moroccan Jew. Parents of her daughter’s classmates pressured her and confronted during school activities over her relationship with the Jewish man, she said. In one case, in March, a father of her daughter’s classmate grabbed the woman by her throat after calling her a “Jew’s whore” and threatening to shoot her at a swimming pool, the report said.
