A police officer was stabbed in the neck at the Flint airport by a man with a knife in what authorities are investigating as a possible act of terrorism. The suspect was immediately taken into custody, and federal prosecutors hours later announced the Canadian man was charged with committing violence at an airport. They identified him as Amor Ftouhi of Quebec.
