TRAVERSE CITY, Michigan (AP) — Authorities said Sunday they are seeking to file terrorism charges and 11 charges of assault with intent to murder against a 42-year-old man accused of carrying out a knife attack at a Walmart store in Michigan.

Chaos unfolded at the Walmart on Saturday after the suspect entered the store during a calm shopping afternoon and randomly stabbed the victims with a pocket knife, authorities say. Minutes after the attack, the suspect was in custody with the help of bystanders at the store.
