A Holocaust survivor, a 10-year-old and a Chabad rabbi were among the 15 people killed when two gunmen opened fire on a Hanukkah event at Australia's Bondi Beach on Sunday. Hundreds of people had gathered to mark the first day of the Jewish festival before the attackers struck at the event in Sydney.

Australian Prime Minister Anthony Albanese has called an attack on a Hanukkah celebration at a Sydney beach that killed at least 11 people an act of antisemitism and terrorism.

A troubling rise in antisemitic attacks and incidents in recent years have left some feeling anger after the kind of deadly attack they felt was sure to happen.

Two people were taken into custody on Sunday as law enforcement officials responded to Australia’s popular Bondi Beach for a "developing incident," the New South Wales Police Force said. Police in a social media message urged the public to avoid the area. Anyone who was there was told to seek shelter.

The group said it already had a list of clients booked for December. Then, when the mass shooting happened in Bondi, Australia​, phones would not stop ringing.

Police said around 1,000 people had attended the Jewish celebration, which was held in a small park off the beach.

Members of Sydney’s Jewish community, and many other Australians, gathered at the site of a mass shooting on Bondi Beach to offer condolences and ask questions.
