On Tuesday, the Islamic State claimed responsibility for the attack at Ohio State University on Monday at its main campus in Columbus, Ohio. A post on the terrorist group's news agency Amaq said the suspect, a Somali refugee who was a U.S. citizen enrolled at the university, "is a soldier" of ISIS, Reuters reported. Abdul Razak Ali Artan, 18, drove a car into pedestrians Monday morning, before exiting the vehicle and slashing people with a butcher knife; eleven people were injured, though none fatally. Artan was shot and killed by a university police officer. White House Press Secretary Josh Earnest said Tuesday the attack may have been "motivated by extremism," though the investigation remains ongoing.
