Investigators are looking into whether a car-and-knife attack at Ohio State University that injured 11 people was an act of terror.

Authorities say the attacker deliberately plowed his car into a group of pedestrians on campus Monday morning, and then got out and began stabbing people with a butcher knife before he was fatally shot by a campus police officer.

The attacker has been identified as Abdul Razak Ali Artan.

A motive is not known, but police say they're investigating whether it was a terrorist attack.

A U.S. official told The Associated Press Monday that Artan was born in Somalia and was a legal permanent U.S. resident. The official was not authorized to discuss the case and spoke on the condition of anonymity.

Classes at Ohio State are scheduled to resume Tuesday.
