There has been a loud explosion in the centre of Paris, police have confirmed.
Emergency services are on the scene in the 9th Arrondissement of the French capital.
Paris police say several people have been injured in an explosion and fire at a bakery believed caused by a gas leak.
A Paris police spokeswoman said several injuries have been reported to police but no deaths, according to Associated Press
Witnesses described on French television the overwhelmingly sound of the blast and people trapped inside nearby buildings.
Interior Minister Christophe Castaner said 'the situation is under control' but warned the explosion had caused a 'heavy toll'.
Speaking Saturday from the scene, he said some 200 firefighters said were involved in the operation.
Scenes around the bakery, shown in images uploaded on Twitter show firefighters at the scene of the blast, which took place on Saturday morning local time.
Firefighters pulled injured victims out of windows and evacuated residents as smoke billowed out of the building on Rue de Trevise in the area of north-central Paris.
The building is around the corner from the Folies-Bergere theater and not far from the shopping district that includes the famed headquarters of Galeries Lafayette.
Silver-helmeted firefighters and red firetrucks filled the street and inspected adjoining courtyards.
Windows of the property look to have been blown out with the force of the explosion and rubble can also be seen out on the streets.
Debris from a burned car and broken glass littered the pavement. A vehicle from gas company GRDF was stationed nearby.
The explosion came amid heavy security in Paris and around France for yellow vest protests expected later Saturday. Although, it's not believed the two are connected.
