Antisemitic incidents have spiked across the U.S. in the year since the Oct. 7 Hamas terrorist attack in Israel — an “avalanche” of disturbing reports as assaults, death threats, Nazi salutes and more have been reported at local schools.

The Anti-Defamation League recorded around 10,000 antisemitic incidents since Oct. 7, marking the largest year-to-year increase since the group started recording such incidents in 1979.

Antisemitic incidents in the U.S. increased 200% in less than one year from the Oct. 7 attacks to September 2024, according to data collected by the ADL Center on Extremism. ADL Center on Extremism Vice President Oren Segal spoke with NBC News’ Christine Roman about why Jewish individuals and institutions were targeted even one day after the attacks.
