A mass shooting during a Hanukkah celebration at Bondi Beach in Sydney, Australia, on Sunday evening left at least 12 people dead and 29 people hospitalized, authorities say.

The annual celebration, known as "Chanukah By The Sea," was scheduled to kick off at 5 p.m. to celebrate the first day of the Jewish holiday by lighting the first candle on the Menorah. Police say the attack "targeted" the Jewish community and is being investigated as an act of terrorism.

The New South Wales Police Force (NSWPF) said officers responded to reports of shots fired at about 6:45 p.m. on Sunday. Police say there were at least two gunmen involved in the attack, and they are investigating the possibility of a third. Twelve people were killed in the shooting, including one of the two suspected gunmen, police said. The second alleged shooter is in critical condition.

At least 29 others were hospitalized after the shooting, including two police officers, the agency confirmed. The shooting is the worst attack against Jews since the Oct. 7, 2023, Hamas terror attacks.

Police added that they found evidence of multiple improvised explosive devices in a vehicle near the scene of the attack.

"We have our rescue bomb disposal unit there at the moment working on that," he said. 

Herzog also called on the Australian government to "seek action and fight against the enormous wave of antisemitism which is plaguing Australian society."
