French police are hunting a suspect following an explosion that wounded 13 people in a busy pedestrian street in the city of Lyon.
Police issued an appeal for witnesses Saturday with a photo of a man with a bike caught on video surveillance.
They describe the suspect, wearing light-coloured shorts and a long-sleeved dark top, as "dangerous."
He is believed to have deposited a sack or package that exploded.
Regional authorities said 13 people suffered mostly minor injuries, including 11 who were still in the hospital on Saturday morning.
