ST. CLOUD (AP) – An Islamic State-run news agency claims the man who stabbed and wounded eight people at a mall in St. Cloud before being shot dead by an off-duty police officer was a “soldier of the Islamic State.”

The IS-run Rasd news agency reported the claim on Sunday, saying the attacker had heeded calls from the extremist group for attacks in countries that are part of a U.S.-led anti-IS coalition.

It was not immediately clear if the extremist group had planned the attack or even knew about it beforehand. IS has encouraged so-called “lone wolf” attacks. It has also claimed past attacks that are not believed to have been planned by its central leadership.

All eight victims from Saturday’s attack were treated at a hospital for wounds that weren’t life-threatening and all but one were later released.
