At least 15 people were killed and more than two dozen injured in a shooting at a Hanukkah event at Bondi Beach in Sydney, authorities said.

Police identified the suspects as a 50-year-old father and his 24-year-old son, with the older suspect fatally shot by officers and the younger hospitalized with critical injuries.

Officials declared the attack an act of terrorism aimed at Jewish people, with victims including a Holocaust survivor, a 10-year-old child, and two rabbis.

Prime Minister Anthony Albanese said the gunmen were inspired by Islamic State ideology and announced the government would consider tightening gun laws and intensifying efforts to combat antisemitism, NBC News has reported.

Ahmed al-Ahmed was praised as a hero for disarming one attacker and is recovering after undergoing surgery for gunshot wounds.
