An attack on a mall in St. Cloud, Minn., is being investigated as a potential act of terrorism, investigators said Sunday.
Nine people were stabbed at the mall Saturday night. Officials told reporters at a news conference Sunday all but three of the victims have been released from the hospital and there are no life-threatening injuries.
"We are currently investigating this as a potential act of terrorism," said Richard Thornton, an FBI special agent based in Minneapolis.
"We don't now whether the suspect was in contact, had connections with, or was inspired by a foreign terrorism organization," he said.
He added the FBI will look at the suspect's social media accounts, his electronic devices and talk to people associated with him.
The suspect was killed at the scene by an off-duty officer.
Media linked to the Islamic State in Iraq and Syria (ISIS) claims the suspect was a soldier of the Islamic State.
The Amaq News Agency said in a statement the attacker "carried out the operation in response to calls to target citizens of countries belonging to the crusader coalition."
Police declined to release the name of the suspect, but community members have identified him as Dahir Adan, a junior at St. Cloud State University who worked as a security guard part time.
Leaders of the Somali-American community in St. Cloud said Adan didn't have a history of violence, according to the St. Cloud Times.
