Police in Sydney are now treating a stabbing at an Assyrian Orthodox Church as a "terrorist attack". At least four people, including a bishop, were wounded in last night's attack in south-west Sydney. A 15-year-old boy has been arrested for the assault at the service, which had been livestreamed. The stabbing comes just days after a fatal attack in a Bondi shopping centre, killing six people. ABC Sydney journalist Brooke Chandler joins me now.
