COLUMBUS- The latest on reports of an attack on the Ohio State University campus Monday:
NBC News reports that the suspect was an 18-year-old Somali refugee who was a permanent U.S. resident. He was a student at Ohio State.
NBC News also reports that the suspect's motive remains unknown, but officials say the attack was deliberate and may have been pre-meditated.
The Associated Press reports witness to an attack at Ohio State University says he initially thought a car had driven over a curb into pedestrians accidentally but realized it was intentional when a man emerged with a butcher knife.
Student Martin Schneider says he saw the attack take place Monday morning.
He says he saw the attacker hit several people with the car, then emerge swinging the knife.
Schneider says the attacker didn't say anything.
He says he heard the car's engine revving before it hit the curb because it was going pretty fast. He says he also heard yells from a frightened crowd.
The AP reports authorities are now saying nine people were injured at Ohio State University when an attacker purposely drove over a curb and into pedestrians and then got out of the vehicle and began stabbing people with a butcher knife.
Ohio State Police Chief Craig Stone says eight of the victims are in stable condition and one victim is in critical condition after the attack Monday.
Authorities said two people had been stabbed, four people had been hurt by a car and two others were treated for lacerations.
The injuries to the ninth person weren't immediately clear.
Earlier, hospital officials said that eight people had non-life-threatening injuries.
Stone says an officer who was nearby because of an earlier gas leak shot and killed the male suspect.

Ohio State's official Twitter page retweeted a post from OSU Emergency Management saying there is an active shooter on campus in Columbus on Monday morning.
The tweet says: "Buckeye Alert: Active Shooter on campus. Run Hide Fight. Watts Hall. 19th and College." Watts Hall is a materials science and engineering building.
"Run, hide, fight" is standard protocol for active shooter situations. It means: Run, evacuate if possible; Hide, get silently out of view; or Fight, as a last resort, take action to disrupt or incapacitate the shooter if your life is in imminent danger.
A Columbus police dispatcher declined to comment on the reports, but police vehicles were seen at the scene.
Several tweets were posted by OSU around 10 a.m. Monday regarding the situation:
"Run Hide Fight," one of the tweets declared.
