Sajid Akram and his son Naveed Akram attacked a crowded Hanukkah celebration on the Bondi Beach promenade at about 18:47 local time, killing 15 people and wounding dozens as bystanders and police moved to stop them.New South Wales Police Commissioner Mal Lanyon and investigators said Sajid held a valid firearms licence, had legally registered six firearms including the shotgun used, and that the pair had recently travelled to the Philippines while officers recovered two Islamic State flags and two improvised explosive devices linked to the attackers.Prime Minister Anthony Albanese called the killings an act of antisemitic terrorism, national leaders agreed to pursue tougher firearms measures including a national firearms register and tighter licence rules, and the Australian Security Intelligence Organisation (ASIO) joined police in investigations that will require international cooperation.
