Anti-Semitic incidents on U.S. college campuses have continued to grow in 2018, with at least 384 recorded incidents in the first half of this year, according to a new report showing the number of genocidal expressions towards Jewish hit new highs on campuses across the United States.

A new report by released Wednesday by pro-Israel organization the AMCHA Initiative, a group that tracks anti-Israel and anti-Semitic activity on college campuses, shows that much of the anti-Semitism on U.S. campuses is the result of activity by anti-Israel activists who promote imagery such as swastikas and tropes calling for the destruction of the Jewish people, according to the report.

Genocidal expression, such as images and language promoting the killing of Jews and destruction of Israel, “rose dramatically” over the past years, with at least 75 percent of such incidents “involving classic anti-Semitism” and “genocidal expression,” according to the report. The number of such incidents appear to have dropped slightly from 2017 to the first part of 2018, the report notes.
