To the Midwestern state of Minnesota, where eight people have been injured after a man went on a stabbing spree at a mall in the city of Saint Cloud.

A hospital spokesman at Saint Cloud Hospital said none of the victims suffered life-threatening injuries. The attacker was shot dead by an off duty police officer.

The lone assailant is reported to have been wearing a private security uniform and had at least one knife. His motive remains unclear and no further details have been provided. The mall has been closed while police continue their investigations.

"That individual made some references to Allah and we have confirmed that he asked at least one person if they were Muslim before he assaulted them," said Blair Anderson, St. Cloud police chief.
