Propaganda Due
In 1977 a commando of Brigate Rosse (communist terrorists) shot him at legs and thorax. Fiori is often included in the list of those belonging to Propaganda Due (P2), a Masonic lodge operating illegally (in contravention of the Italian constitution banning secret lodges, and membership of government officials in secret membership organizations) from 1976 to 1981. In 2001, however, the Court of Rome ruled out his membership of P2.
