A priest has been stabbed during morning mass at a church in Montreal that was being broadcast live online and on television.
At around 8.40am, Father Claude Grou was conducting the service at Saint Joseph's Oratory when the attacker, who has not been named, suddenly rushed at him from one of the pews.
He ran towards the priest, stabbing him in the upper body, as members of the congregation watched on in horror.
Father Grou fell to the ground but got back up immediately as worshipers stood between him and the attacker to put distance between them until police arrived.
The attacker has not been named or charged. He was taken into custody and will be interviewed this afternoon.
It remains unclear what his motive was.
