At least nine people were injured Monday morning when an attacker drove a car into a crowd on the campus of Ohio State University, got out of the vehicle and began stabbing and slashing people with a large knife, Columbus Police say. The suspect, identified as 18-year-old Somali refugee Abdul Razak Ali Artan, was killed by police at the scene. The chaotic attack led to a campus wide lockdown as an "active shooter" alert told students and faculty to "run, hide, fight" because of the threat to the campus. One of the victims injured in the attack was in critical condition, while the others were reported to be stable. Click through the gallery to see more photos from the scene.
