When a suspect walked into the home of a rabbi celebrating Hanukkah and stabbed five celebrants it was the latest in a week of anti-Semitic attacks in the nation’s most demographically diverse area — and an incident that reverberated across the country.

“Again, here we are: mourning another act of senseless anti-Semitic violence committed against our community and praying for those who were the victims of this hate,” Anti-Defamation League CEO Jonathan Greenblatt said in a statement Sunday following the attack a day earlier in Monsey, New York.
