SYDNEY, Dec 15 (Reuters) - Two alleged gunmen who killed 15 people at a Jewish celebration at Sydney's Bondi Beach were a father and son, police said on Monday, as Australia began mourning victims of its worst gun violence in almost 30 years.

Once again, Jewish people were targeted and attacked on a major religious holiday, marking the latest escalation in an antisemitism epidemic.

At least 11 people were killed at a Jewish gathering on Australia's Bondi Beach, according to Australian government officials and police. One of two gunmen was also dead.

SYDNEY, Dec 15 (Reuters) - Stories of horror and heroism emerged as Australians mourned the 15 people killed by two gunmen at Sydney's Bondi Beach during a Hanukkah event.

An investigation is underway after a deadly attack on a Hanukkah event at Bondi Beach in Sydney, Australia, on Sunday.

The deadly shooting during a Hanukkah celebration at Australia's Bondi Beach follows a sharp rise in antisemitic attacks in the country since the Hamas-led assault on Israel on Oct. 7, 2023, and the ensuing war in Gaza.

Two gunmen opened fire during a Hanukkah celebration on Sydney’s Bondi beach, killing 15 people, including a child, officials said Monday, in what Prime Minister Anthony Albanese called an act of antisemitic terrorism that struck at the heart of the nation.

Chabad-Lubavitch Headquarter's Rabbi Yehuda Krinsky says the Bondi Beach shooting reflects Australia's tolerance of escalating antisemitic violence.

The shooting, which Australian authorities have declared a terror attack, targeted hundreds of people celebrating Hanukkah

Two gunmen killed at least 11 people during a Hanukkah event Sunday on Sydney’s Bondi Beach, in what officials called a terrorist attack on Australia’s Jewish community. One suspect was also killed and the other is in critical condition.

Video appears to show a man tackling and disarming one of the gunmen, as officials say 11 people were killed in an attack "designed to target" Jewish people.
