The FBI is investigating whether the man who drove his car into pedestrians before attacking people with a butcher knife at Ohio State University Monday has ties to radical Islamic groups.

The attacker, 20-year-old Abdul Razak Ali Artan, was a Muslim Somali refugee who was killed by police at the scene.

The Islamic State militant group has claimed responsibility for the attack, and President-elect Donald Trump tweeted about the events yesterday.

Here & Now's Jeremy Hobson speaks with Hassan Omar, director at the Somali Community Association of Ohio, about how the community is reacting to Monday's attack.
