Man arrested in Canada after possible terrorist attack

A police officer was first hit by a car and then stabbed by its driver on Saturday evening near Commonwealth Stadium, and four pedestrians were injured by a truck driven by the fleeing assailant.
 
Police are investigating the attacks as acts of terrorism.
 
“We believe the individual acted alone,” Edmonton Police Service Chief Rod Knecht said on Sunday. However, he added that police would also investigate possible involvement by others.
 
The condition of the four pedestrians was unknown. Knecht said the attacked officer was not critically injured.
 
He confirmed that a Daesh flag had been seized from the vehicle connected with the attack on the police officer.
 
Knecht said the officer was standing behind a barricade when a Chevrolet Malibu crashed into it and hit the officer. The driver then jumped out of the car and stabbed the officer with a knife “several times” before fleeing the scene on foot, prompting a massive manhunt, Knecht said.
 
Approximately two hours later, the suspect was found by police driving a U-Haul van.
 
This led to a high-speed chase through downtown Edmonton with up to a dozen police vehicles in pursuit, ending with the U-Haul crashing into a crowd.
 
The incidents had the hallmarks of recent terrorist attacks by Daesh in Europe.
