The Islamic State issued this call in September 2014:
So O muwahhid, do not let this battle pass you by wherever you may be. You must strike the soldiers, patrons, and troops of the tawaghit. Strike their police, security, and intelligence members, as well as their treacherous agents. Destroy their beds. Embitter their lives for them and busy them with themselves. If you can kill a disbelieving American or European — especially the spiteful and filthy French — or an Australian, or a Canadian, or any other disbeliever from the disbelievers waging war, including the citizens of the countries that entered into a coalition against the Islamic State, then rely upon Allah, and kill him in any manner or way however it may be….If you are not able to find an IED or a bullet, then single out the disbelieving American, Frenchman, or any of their allies. Smash his head with a rock, or slaughter him with a knife, or run him over with your car, or throw him down from a high place, or choke him, or poison him….

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 of them were later released.
Eight people were injured during a stabbing attack at a Minnesota shopping mall that ended with the suspected attacker – who was dressed in a private security uniform and made references to Allah – shot dead by an off-duty police officer, authorities said….
