The Anti-Defamation League’s audit of anti-Semitic events counted 541 anti-Semitic attacks and threats against Americans in the first quarter of the year, a dramatic increase over the same period last year.

The incidents followed an overall 34% increase in anti-Semitic assaults, vandalism and harassment last year when compared with 2015, according to the report.

The surge in anti-Semitic incidents in the United States came against an overall drop in such incidents worldwide, according to a report issued Sunday by the Kantor Center for the Study of Contemporary European Jewry at Tel Aviv University.

The Kantor report, which surveyed approximately 40 countries, said incidents of anti-Semitism dropped 12% globally. In France, home to Europe’s largest Jewish community, reports of anti-Semitic acts dropped 61%. However, the English-speaking world in general bucked the trend, with increases in Britain, Australia and, especially, the United States. The report noted that anti-Semitic incidents on U.S. college campuses rose by 45%.
