Leading Jewish groups in the United States are urging all Jewish organizations to ratchet up security measures at public events � including restrictions on access � following the deadly�mass shooting that targeted a Chanukah celebration on a popular Australian beach.

The groups�� including three which specialize in security issues � said Jewish public events in the coming days should be open only to people who had been screened after preregistering.

�Provide details of location, time, and other information only upon confirmed registration,� the groups� advisory said. �Have access control (locks and entrance procedures) to only allow known, confirmed registrants/attendees into the facility/event.�

At least 15 people died in Sunday’s attack, which has fueled criticism that the nation�s authorities were not doing enough to combat a�surge in antisemitic crimes. On Monday, Australian leaders promised to overhaul already-tough�gun control laws�after the targeted attack on Sydney�s Bondi Beach

Among those killed was Eli Schlanger hy”d, assistant rabbi at Chabad of Bondi and an organizer of the family Chanukah event.

Just a year earlier, Rabbi Schlanger had urged his fellow Jews to be uncowed in the face of rising antisemitism, voicing this message, �Be more Jewish, act more Jewish and appear more Jewish.�

Chabad centers worldwide are going ahead with thousands of planned public menorah lightings and community Chanukah celebrations �while taking greater security precautions � calling on the Jewish community to drown out hate with greater light and goodness while mourning those lost and wounded in Sydney.�
