Canadian police are treating as acts of terror a multiple attack Sunday by a man, who rammed a police car in Edmonton before stabbing an officer several times. Police chief Rod Knecht confirmed there was an Islamic State flag on the car. He then fled the scene, using a truck in which he ran down pedestrians. Four were injured.
The suspect was caught after a high-speed chase during which the truck overturned. Police pulled him out and handcuffed him. They believe the attacker acted alone but did not rule out the involvement of others.
