A Somali immigrant who injured 11 people at Ohio State University in a vehicle and stabbing attack before he was shot dead may have followed the same path to self-radicalization as militants in a number of “lone wolf” attacks, U.S. officials said on Tuesday.
The Islamic State militant group claimed responsibility on Tuesday for the attack.
Abdul Razak Ali Artan, 20, was shot dead by a police officer on Monday moments after he plowed his car into a crowd of pedestrians and then leapt out and began stabbing people with a butcher knife.
Investigators were probing the background of Artan, a Muslim who was a lawful permanent resident of the United States and a student at Ohio State.
Police have given no motive for the attack on the Columbus campus.
