Bishop Mar Mari Emmanuel was stabbed repeatedly at a mass at the Assyrian Christ the Good Shepherd church in Wakeley just after 7pm on Monday.
A live stream of the mass on the church’s website showed a person approaching the altar who then appeared to stab toward the bishop’s head multiple times.
The 16-year-old perpetrator is in police custody. He made reference to “his religion’ which causes authorities to declare this was a terrorist event
