Police say at least four hostages have been killed at kosher supermarket in the north east of Paris, with the gunman dead after a dramatic rescue operation by special forces.
Shortly afterwards gunfire and explosions were heard as police moved in to the industrial estate, with similar scenes at the deli around 10 to 20 minutes later.
Pictures are emerging of what appeared to be flash-bang explosions, designed to distract hostage takers before a major rescue operation.
Just before 5pm Reuters reported that at least five hostages had been killed.
