At least eight people were injured during a mass stabbing in a St. Cloud, Minnesota, shopping mall on Saturday night. The attack happened at the Crossroads Center. The attacker, who was shot and killed by an off-duty police officer, wore a security uniform and "made references to Allah while attacking," The Associated Press reports. One victim remains hospitalized but none of the injuries are life-threatening, authorities said. St. Cloud Police Chief Blair Anderson said the suspect, who has not been named, was known to police for minor traffic violations. A motive has not been identified, and Anderson would not say the attack was an act of terrorism.
