Fifteen people, including a 10-year-old boy, were killed and 42 others injured in an attack on a Jewish community at Bondi Beach, Australia, authorities said on Sunday. The incident occurred during celebrations of Hanukkah, the eight-day Jewish Festival of Lights.

New South Wales Police Commissioner Mal Lanyon identified the attackers as a father and son, aged 50 and 24. The elder man held a firearms licence and had six registered firearms, all of which are believed to have been used in the attack.

The first day of Hanukkah festivities was underway when the assault took place, leaving the local community and emergency services responding to a scene of widespread casualties.

Police have launched a full investigation into the attack, while authorities work to provide support to victims and their families.
