The attack on Sydney’s Bondi beach that killed at least 15 people brutally interrupted one of the first of 15,000 public lightings around the world of a menorah, a multi-branched candelabrum central to Judaism, to mark the start of the eight-day Hanukah festival. The annual global lightings are organised by the Chabad-Lubavitch movement, a branch of Orthodox Hassidic Judaism whose visibility as a vibrant, open and outgoing community appears to have made it a target for hate.
