The two gunmen who opened fire on Australia’s Bondi Beach where thousands of Jews were celebrating Hanukkah are believed to be a father-son duo who had a trove of legally-owned guns.

Naveed Akram, 24, and his 50-year-old accomplice are believed to be father and son, authorities said on Monday.

The father was killed at the scene during a shootout with police, while Akram is in the hospital after being critically wounded by cops.

Together they allegedly murdered at least 15 people ranging in age from 10 to 87 years old, most of whom are believe to be Jewish.

They owned at least six guns between them, each of which were fully licensed.

The shooting — which appears to have involved shotguns and a bolt-action rifle — come despite Australia cracking down on firearms following the 1996 Port Arthur mass shooting.

Semi-automatic rifles were banned and the country enacted strict registration and purchasing restrictions for all weapons.

The Bondi attack is the deadliest mass shooting in Australia since Port Arthur, which left 35 dead and 24 wounded.

Sunday’s attack went down in the evening on the popular Sydney beach, where about 1,000 people had gathered to celebrate the first day of the Jewish holiday.

Screams could be heard between loud gunshots as people struggled to wrap their heads around what was happening and then fled for cover.

The gunfire continued for 10 terrifying minutes before a local fruit seller – 43-year-old Ahmed al-Ahmed — snuck up on Akram and tackled him to the ground.

In addition to children, a rabbi and even a Holocaust survivor were among the victims so far.

Nearly 40 people were injured in addition to the fatalities so far.
