The Secure Community Network, which coordinates security for Jewish institutions nationwide, said early Sunday that it had tracked 199 threats over the past 24 hours, with nearly 100 in California and 62 in Arizona. Synagogues in at least 17 states plus Washington, D.C., were affected, according to local media reports. The Anti-Defamation League has reported an increase of over 330% in the number of antisemitic incidents in the US in the weeks since the Hamas massacre of over 1,200 people in southern Israel on October 7. "Gas the Jews," a reference to the gas chambers used during the Nazi Holocaust, was chanted at an anti-Israel rally celebrating the Hamas massacre in Sydney Australia just a few days after the massacre, and has come to symbolize the antisemitism inherent in anti-Israel protests which have taken place around the world in the aftermath of the massacre.
