A 37-year-old man is facing a federal charge after bullet primers ignited in his bag as it was being unloaded at Miami International Airport from a flight that had just arrived.

FBI spokesman Mike Leverock says there is no connection to terrorism. The man is a naturalized U.S. citizen who was traveling Tuesday on an American Airlines flight from Boston to Miami and on to Jamaica. His name was not immediately released.

Leverock says several hundred bullet primers were discovered inside the bag after some ignited. No one was injured, although a few small shards struck the shoe of a baggage handler.

The man was being held on a charge of traveling in interstate commerce without a license to carry ammunition.
