Two suspected gunmen accused of killing 15 people and injuring dozens during a Hanukkah celebration in Australia have been identified as a father and a son, authorities said. The younger man was reportedly investigated years ago over suspected links to an ISIS cell in Sydney,

Australian police said on Tuesday that the two alleged gunmen behind the mass shooting at Sydney's Bondi Beach travelled to the Philippines last month, and that the reasons for their trip were under investigation.

Among the 15 victims of a mass shooting at Australia's Bondi Beach during an event for the Jewish festival of Hanukkah on Sunday were a rabbi, a Holocaust survivor and a 10-year-old girl, according to interviews,

Three decades ago, almost 650,000 firearms − about one-third of all privately owned guns in Australia – were surrendered, loaded intro trucks and destroyed. In exchange for these firearms, part of a mandatory gun buyback program, the government paid out $200 million. Gun-related murder and suicide rates plummeted.

The hero who took out one of the accused Bondi Beach terrorists was identified as a seasoned local detective who fired a kill shot from over 100 feet away, according to reports.

More than two dozen others were injured in the attack, which police say they are treating as a terrorist incident.
