Mourners on Thursday laid to rest the youngest victim of the Bondi Beach attack in Sydney: 10-year-old Matilda, who had been enjoying the Hanukkah festivities with her family when the gunmen opened fire.

Ahmed al Ahmed, the Syrian-Australian father who wrestled a shotgun from one of the gunmen attacking a Jewish gathering, is facing a long road to recovery.

When shots ran out at a Hanukkah celebration on Australia's Bondi Beach, Arsen Ostrovsky said he thought it could've been balloons popping.

The attack in Bondi Beach was carried out by a father and son, and according to authorities, appeared to have been inspired by Islamic State, Reuters reported.

The attack was Australia's worst mass shooting in nearly 30 years, and is being investigated as an act of terrorism targeting the Jewish community.

People of all ages had been looking forward to celebrating — especially this year, as a ceasefire in Gaza has held since October and all but one of the hostages taken by Hamas-led militants have been returned.

The 24-year-old, along with his father Sajid Akram, shot dead 15 people and injured at least 40 others in an attack at Bondi Beach.
