Chicago - A knife attack on a Michigan airport police officer Wednesday by a man yelling "Allahu Akbar" is being investigated as an act of terrorism, the FBI said. The stabbing at Bishop International Airport, in the city of Flint, comes amid a wave of jihadist-inspired attacks in Europe, most recently a foiled bomb assault at a train station in Belgium. US officials identified the suspected assailant, who is in custody and cooperating with investigators, as a 49-year-old Canadian resident from Quebec named Amor Ftouhi. "We're investigating this incident today as an act of terrorism," FBI special agent David Gelios told a news conference, detailing Ftouhi's actions on Wednesday morning based on security camera footage. Ftouhi was seen lingering with luggage around the airport's non-secured public areas, including at a second-floor restaurant and a bathroom, before pulling out a 12-inch serrated-blade knife, yelling "Allahu Akbar" and stabbing an officer in the neck, police said. During the attack, Ftouhi "referenced killings in Syria, Iraq, and Afghanistan," according to a press release from the US Attorney's Office for the Eastern District of Michigan.
