French President Emmanuel Macron said the bomb was an “attack" and sent thoughts for the injured.

"It's not for me to give a toll but it appears there are no casualties. There have been injuries, so obviously I'm thinking of these injured and their families," Macron said.

Le Progrès, a French newspaper based in Lyon, said the parcel bomb was filled with nuts, bolts, and screws.

Reports say a man riding a bicycle dropped the "parcel" off in front of the bakery minutes before it went off.
