Dec. 21 (UPI) -- Seven days after a mass shooting devastated Bondi Beach, Australians gathered on Sunday for a national day of reflection.

The commemorations come as Prime Minister Anthony Albanese faces intense public scrutiny and has ordered an urgent investigation into the nation's intelligence and police frameworks.

The tragedy, which claimed 15 lives during a Hanukkah seaside event, is the deadliest mass shooting Australia has seen in nearly three decades.

Authorities have officially classified the massacre -- which killed a 10-year-old girl, a British rabbi and a Holocaust survivor, among others -- as a terrorist act aimed at the Jewish community.
