15-year-old boy stabbed an Orthodox bishop in a church on the western outskirts of Sydney. NSW Police Commissioner Karen Webb said the attack was considered an act of religiously motivated "extremism" The suspect was "known to police" but was not on any terrorist watchlist, Webb said.

Officers responding to the incident soon found themselves attacked by angry people outside the church, she added. "People used what they had available in the area, including bricks, concrete, palisades, to attack the police and launch missile attacks at the police, their equipment and vehicles," Webb said at a news conference. The mob had damaged 20 police vehicles, she said, adding that the injured officers were taken to hospital overnight, without giving figures. "Those who were involved in that riot can expect someone to come knocking on their door. It may not be today, but we will meet you and we will come and arrest you," Webb assured, without saying when she would make an arrest.
