Paris (CNN) At least seven people were hurt Friday in an explosion in the French city of Lyon, prompting a national investigation into possible terrorism. The blast occurred in the early evening in the city's central shopping area, and authorities were searching for the culprit. French President Emmanuel Macron characterized the blast as an attack shortly after it happened, telling an interviewer: "I'm late because there was an attack in Lyon." Emergency workers wheel a woman on a stretcher to a waiting ambulance in Lyon on Friday. Investigators believe the explosion may have been caused by a parcel bomb packed with nails, a spokeswoman for the city prosecutor told CNN.
