Italian Anarchist Federation

Inside the FAI a tendency grouped as (GAAP - Anarchist Groups of Proletarian Action) led by Pier Carlo Masini was founded which "proposed a Libertarian Party with an anarchist theory and practice adapted to the new economic, political and social reality of post-war Italy, with an internationalist outlook and effective presence in the workplaces...The GAAP allied themselves with a similar development within the French Anarchist movement, the Federation Communiste Libertaire, whose leading light was Georges Fontenis.

"[1] In the IX Congress of the Italian Anarchist Federation in Carrara, 1965 a group decided to split off from this organization and creates the Gruppi di Iniziativa Anarchica which was mostly composed of individualist anarchists who disagreed with important aspects of the "Associative Pact" and was critical of anarcho-syndicalism.

Another group split off from the Anarchist Federation and regrouped as Gruppi Anarchici Federati.

[3] Other media outlets attributed the bombs to another group, the insurrectionist Informal Anarchist Federation.
