CHICAGO (AFP) - The FBI said on Wednesday (June 21) that it is investigating the stabbing of a police officer at a Michigan airport on Wednesday morning as an "act of terrorism."

The suspect, who is in custody and cooperating with investigators, is a Canadian resident in his 50s named Amor Ftouhi, FBI special agent David Gelios told a news conference.

Authorities were conducting joint operations in Canada and the US in the wake of the non-fatal stabbing at Bishop International Airport in Flint, Michigan, Gelios said.

Ftouhi, described by police as having a "hatred for the United States," is accused of stabbing airport officer Jeff Neville in the neck with a 12-inch knife in the public area of the airport.

The officer was in stable condition after undergoing surgery.

President Donald Trump was briefed on the stabbing, which federal investigators believed to be "an isolated incident."

The injured police officer was identified as Jeff Neville.

NBC News reported that the suspect stabbed him multiple times while shouting "Allahu Akbar" - which means "God is greatest" in Arabic.

At the airport, dogs were observed examining cars in the parking lot, and groups of passengers were escorted with bags at hand, according to the local NBC TV affiliate.

NBC News cited law enforcement officials as saying the suspect was from Quebec and has a Canadian passport.

The victim, Neville, who was reportedly stabbed in the back and neck, is a 16-year veteran of the airport's police force with a rank of lieutenant. Before that, he served as a sheriff's deputy for 17 years in Genessee County, where Flint is located.
