The victims range in age from 10 to 87, Australian authorities confirmed, and include religious leaders, devoted friends and beloved family members.

"Please say Psalms 20 & 21 for my son, Rabbi Leibel Lazaroff, who was shot in a terrorist attack at a Chanukah event he was running for Chabad of Bondi in Sydney, Australia," Yossi Lazaroff wrote Sunday. "The Chabad Rabbi he was working with Rabbi Eli Schlanger was killed. Praying for all the victims and their families."

The incoming comptroller of New York, Mark Levine, who urged Jewish New Yorkers to attend menorah lightings earlier in the day, told the crowd that none of the public Hanukkah events throughout the city had been cancelled and that “turnout has been off the charts.”
