At least nine people have been injured, and the suspect killed, following an attack at Ohio State University in the United States.
A man rammed his car into a group of pedestrians at Ohio State University then got out and began stabbing people before he was shot dead by police.
Nine people were hurt, one critically, in the rampage at the campus in the state capital of Columbus.
Police Chief Kim Jacobs said they were investigating whether it was a terrorist attack.
Federal agents and police responded to the incident at the 60,000-student campus.
Law enforcement officials quoted by NBC News said the attacker was an 18-year-old Ohio State student, a Somali refugee who was a legal permanent resident of the US.
The incident began at 10:00 local time on Monday when a vehicle jumped the kerb at the campus, striking pedestrians near Watts Hall, the science and engineering building.
Ohio State Police Chief Craig Stone said the driver got out of the vehicle and began stabbing bystanders with a “butcher’s knife”.
