At least eight people have been injured in an explosion in the French city of Lyon, according to the regional authority.
The prosecutor’s office said a suspected parcel bomb was the cause of the explosion.
None of the injuries are life-threatening, it added.
The Paris counter-terrorism prosecutor has opened a probe into the blast.
“I was a block away and I heard it. They locked us in the store. I came out 10 minutes later and the police etc were arriving,” Canadian travel writer Kathy Buckworth told Euronews.
The explosion was “like a bomb, extremely loud,” she said.
