The terror group Islamic State (Isis) says it was behind an attempted terror attack at Ohio State University (OSU) on Monday 28th November in which a suspect was shot dead. The suspect, 18-year-old Somali refugee Abdul Razak Ali Artan, was killed within two minutes of launching his attack on the Columbus Campus, driving at students before attacking them with a butcher's knife.

Amaq News Agency — often used by the jihadist group to issue claims of responsibility - says 18-year-old Artan was "a 'soldier of the Islamic State." Earlier the FBI had said it was too early to tell if he had acted on political or religious grounds, despite leaving a number of Facebook posts which hinted at radicalisation.

In a post apparently written shortly before carrying out his attack, Artan said he was acting to warn the US "to stop interfering with other countries, especially the Muslim Ummah. By Allah, we will not let you sleep unless you give peace to the Muslims. You will not celebrate or enjoy any holiday."

Artan was killed by Ohio State University Police Officer Alan Horujko before he could kill anyone, and all the injured are expected to survive. The campus was put on lockdown for an hour following the incident.

According to CNN Artan left Somalia with his family in 2007, moving first to Pakistan. In 2014 the family moved to Columbus, which has a relatively large Somali population. Artan had enrolled at OSU to study logistics. The fact that Artan was apparently a former refugee seems certain to reignite the debate about Muslim immigration to the US, which President-elect Donald Trump referred to repeatedly during his campaign.
