SYDNEY, Dec 16 (Reuters) - While a Sydney shopowner is being hailed as a hero after disarming one of the gunmen shooting at a Jewish holiday event at Sydney’s Bondi Beach, a couple and another man who died after physically confronting the attackers are also being remembered for their heroic efforts to save those around them.

Australian leaders have promised to immediately overhaul already-tough gun control laws after a mass shooting targeted a Hanukkah celebration on Sydney’s Bondi Beach.

A Holocaust survivor, a 10-year-old and a Chabad rabbi were among the 15 people killed when two gunmen opened fire on a Hanukkah event at Australia's Bondi Beach on Sunday. Hundreds of people had gathered to mark the first day of the Jewish festival before the attackers struck at the event in Sydney.

Dashcam video emerged Tuesday showing two bystanders trying to disarm one of the suspected gunmen before they carried out their horrific attack on a Hanukkah event attended by hundreds of families, killing at least 15 people.

In the minutes that followed the first sounds of gunfire Sunday night at Bondi Beach in Sydney, the assault would end the lives of at least 15 people.

Naveed Akram, 24, was charged Wednesday after waking from a coma in a Sydney hospital, where he has been since police shot him. His father, also shot, died.
