Antisemitism in the United States — already at a record high — has skyrocketed since the start of the October 7 war against Israel by Hamas. But it has also leaped in other countries as well.

According to a report released Tuesday by the New York-based Anti-Defamation League (ADL), at least 312 antisemitic incidents were reported between October 7 and October 23, a jump of nearly 400 percent over the same period in 2022.


Preliminary data from the ADL Center on Extremism indicates that reported incidents of harassment, vandalism and assault increased by 388 percent over the same period last year.

The figure includes 109 anti-Israel rallies that have taken place since Oct. 7 in which the “protesters” expressed explicit or strong implicit support for Hamas and/or violence against Jews in Israel.

“When conflict erupts in Israel, antisemitic incidents soon follow in the U.S. and globally,” noted ADL CEO Jonathan Greenblatt.

The ADL has also created a H.E.A.T. Map™ (Hate, Extremism, Antisemitism, Terrorism), a first-of-its-kind interactive and customizable map detailing specific incidents of hate, extremism, antisemitism and terrorism by state and nationwide that is updated monthly.

ADL also recorded a nearly 1,000-percent increase in the daily average of violent messages mentioning Jews and Israel in white supremacist and right-wing extremist channels on the messaging platform Telegram in the days following the Hamas massacre of innocent civilians in Israel.

“It is incumbent on all leaders, from political leaders to CEOs to university presidents, to forcefully and unequivocally condemn antisemitism and terrorism,” Greenblatt said. “This isn’t hard. Words matter, and while the war in Gaza escalates, we encourage all those in positions of power to use their platforms to condemn hate and terrorism, wherever it occurs.”
