Notre-Dame fire: Prosecutor says no sign of criminal cause
French authorities say they have no reason to believe that criminal action was to blame for a fire that tore through the iconic Notre-Dame cathedral in April.
The cause of the blaze remains unknown, but investigators are now probing the possibility of negligence.
A "badly stubbed out cigarette" or electrical fault are among the possible causes being considered.
