A terrorist attack in the heart of the French city of Lyon has injured at least 13 people.

Iran Press/Europe: A blast in rue Victor Hugo has wounded at least 13 people, including a young girl, Le Figaro newspaper wrote citing well-informed sources.

The explosion is believed to have been caused by a "parcel bomb" filled with "nails, screws and bolts" dropped off by a man on a bike, local newspaper Le Progres said.

Le Progres wrote: "According to our information, the package, filled with nails, screws and bolts, was laid in the street."

Several eye-witnesses saw a man on a bike dropping off a suitcase in front of a bakery, le Brioche Doree. The package exploded just a couple of minutes later.

The suspect is now wanted by the police, Le Figaro wrote quoting Aurélie Bonnet Saint-Georges, deputy mayor of the 2nd district of Lyon where rue Victor Hugo is located.

She said: "It's a man in his thirties, who deposited with his face covered a package in rue Victor-Hugo. 

"The video surveillance images are being studied by police right now, the police will also recover CCTV footage of the hotels in the street, to trace the path of the individual upstream."

The blast took place approximately at 4.30pm BST (5.30pm local time), near number 16 on rue Victor Hugo.

The explosion has been labelled a 'terror attack' by Marine Le Pen.

Marine Le Pen, leader of right-wing National Assembly, labeled the explosion a "terrorist attack" on Twitter, saying: "I give my full support to the wounded in an explosion in Lyon, the light will have to be shed on the circumstances of this terrorist attack."
