WASHINGTON, Nov. 29 (Xinhua) -- Extreme group Islamic State on Tuesday said the attacker who injured 11 people on Ohio State University (OSU) campus Monday was a "soldier of the Islamic State."

The attacker carried out the operation in response to calls to target citizens of international coalition countries, the self-fashioned caliphate said in an online message.

According to media reports, the group recently released a video calling on attacks on the West and demonstrated how to kill people with knives.

It is unclear if the group had any ties with the attacker, identified by local police as Abdul Artan, an 18-year-old OSU student who moved to the United States from Somalia.

Artan was shot and killed by police shortly after he drove a car into pedestrians and started attacking people with a butcher knife.

The Islamic State, which operates mainly in Syria and Iraq, is considered a terrorist group by the U.S. government. It is known to claim responsibilities to violent attacks as a propaganda method to forward its ideology, exert influence, and attract potential followers.
