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.

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.

"There are many, many people alive tonight as a result of his bravery," Chris Minns, the premier of New South Wales state, said.

New South Wales Premier Chris Minns said the attack "was designed to target Sydney's Jewish community on the first day of Hanukkah."
