Authorities in Australia have charged a 24-year-old man in connection with the shooting at a Hanukkah celebration in Bondi Beach on Dec. 14 that killed 15 people and injured 41 others, including four children.

A mass shooting in which 15 people were killed during a Hanukkah celebration at Sydney's Bondi Beach was "a terrorist attack inspired by Islamic State," Australia's police said Tuesday.

An Australian bystander who stomped on the head of one of the men accused in the Bondi Beach mass shooting has said he feels no remorse for his actions, describing them as an instinctive response to the scenes he had just witnessed.

Australia’s deadliest mass shooting in almost 30 years targeted Jewish families on Sydney’s Bondi Beach, one of the country’s most iconic locations, on one of the most festive days of the Jewish calendar.

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.
