French police are hunting for the person who left a suitcase in front of a bakery in Lyon on Friday just before an explosion injured 13 people, officials said.

The partially masked person was captured on security video wheeling a bicycle before leaving the suitcase in front of the Brioche Doree bakery, where the blast later rained metal bolts on passersby around 5:30 p.m. local time, police sources and local mayor Denis Broliquier told Reuters.

Interior ministry officials initially said eight people had been injured, but police sources later put the number hurt at 13, with none of the injuries thought to be life-threatening.

President Emmanuel Macron, who was beginning a broadcast address as news of the explosion broke, described the incident as an "attack" with no fatalities.

Live television images of the street showed the Brioche Doree sign intact and police vans and an ambulance at the scene.

The central area, the Presqu'ile, lies between the Rhone and Saone rivers that run through France's third-largest city.

Macron sent his thoughts "to the injured and their families."

The women's World Cup soccer tournament is scheduled to start in France on June 7. Lyon will host the semifinals, and then the final on July 7.

French Interior Minister Christophe Castaner said in a tweet that he has sent instructions for Lyon authorities to strengthen "the security of public sites and sporting, cultural and religious events."
