Canada probing 'terrorist attack' that injured several

Police have detained a suspect accused of ramming his vehicle into a police officer before stabbing him and fleeing on foot. The same suspect is believed to have later crashed a separate vehicle into pedestrians before ultimately being apprehended.

None of the victims were killed in the attack in Canada's western Alberta province, but the police officer and four of the pedestrians were hurt.

Canadian police have said the suspect is a Somali national who had been seeking refugee status.

"While the investigation continues, early reports indicate that this is another example of the hate that we must remain ever vigilant against," Prime Minister Justin Trudeau said in a statement on Sunday.

According to broadcasters CBC and CTV, a flag belonging to the "Islamic State" was found inside the vehicle that hit the police officer.

Suspected 'lone wolf' attack

The alleged attack happened on Saturday night outside a Canadian Football League game at Edmonton's Commonwealth Stadium.

Edmonton Police Chief Rod Knecht said the suspect is likely to have acted alone, but they have not ruled out the possibility that others were involved.

Edmonton Mayor Don Iveson said the authorities believed there was no further threat and that it had been a "lone wolf" attack.
