The gunmen behind the mass shooting at a Jewish celebration in Sydney were motivated by “Islamic State ideology,” Australia’s leader said on Tuesday.

A Holocaust survivor, a 10-year-old and a Chabad rabbi were among the 15 people killed when two gunmen opened fire on a Hanukkah event at Australia's Bondi Beach on Sunday. Hundreds of people had gathered to mark the first day of the Jewish festival before the attackers struck at the event in Sydney.

Australian Prime Minister Anthony Albanese says his government will crack down on hate speech following Sunday's deadly shooting at Bondi Beach that targeted a Jewish festival.

All the victims identified so far were Jewish, ranging in age from a 10 year old girl to an 87 year old Holocaust survivor.

Alex Carey posted a hometown hundred and Usman Khawaja scored 82 after a dramatic, last-minute recall to help Australia reach 326 for eight at stumps on a hot opening day of the third Ashes test.

Cricket Australia boss Todd Greenberg on Thursday called an error in the Snicko technology being used during the Ashes "not good enough" as England had a review reinstated over the row.

Carey was ably backed by Usman Khawaja, who capitalised on his late inclusion in place of an unwell Steve Smith by scoring 82 off 126 balls.
