The attacker, whom officials have identified as 18-year-old Abdul Razak Ali Artan, drove into a group of pedestrians on OSU's campus before using a knife to cut people.

Eleven people were sent to the hospital with injuries. A campus police officer killed Artan at the scene.

Amaq, ISIS's unofficial news agency, released a statement on Tuesday saying ISIS was responsible for the attack.

The Amaq statement identified Artan as a "soldier" of ISIS.

There is now a channel on the encrypted messaging app Telegram, which is frequently used by ISIS supporters to spread propaganda, dedicated to Artan.
