Australian officials said the shooting at a Jewish holiday celebration had been carried out by a father and son. More than three dozen people were hospitalized, including a surviving gunman.

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.

At least 11 people were killed on Sunday by gunmen who targeted a Jewish holiday celebration at Bondi Beach in Sydney, Australia.
