Yves Guérin-Sérac

Yves Guérin-Sérac (alias Jean-Robert de Guernadec, alias Yves Guillou, alias Ralf) (1926-) was a French anti-Communist Roman Catholic activist, former officer of the French army and veteran of the First Indochina War (1945–54), the Korean War (1950–53) and the Algerian War of Independence (1955–62). He was also a member of the elite troop of the 11ème Demi-Brigade Parachutiste du Choc, which worked with the SDECE (French intelligence agency) and a founding member of the Organisation armée secrète (OAS) a terrorist group which fought against Algerian independence in 1961-62. It had been alleged that he was an instigator of the so-called strategy of tension in Italy, and the main organizer of the 1969 Piazza Fontana bombing.

Iberian peninsula
In June 1962, after the 18 March 1962 Evian Accords that put an end to the Algerian War, Yves Guérin-Sérac was engaged by Franco to engage in operations against the Spanish opposition. He then worked for Salazar's Estado Novo regime in Portugal, which, beside being the last colonial empire, was also in his eyes the last stronghold against communism and atheism: "The others have laid down their weapons, but not I. After the OAS I fled to Portugal to carry on the fight and expand it to its proper dimensions - which is to say, a planetary dimension." Guérin-Sérac met Petainist Jacques Ploncard d'Assac in Portugal who introduced him to the right-wing establishment and to Portugal's secret police, the PIDE. Due to his extensive knowledge, Guérin-Sérac was recruited as instructor for the paramilitary Legião Portuguesa and for the counterguerrilla unit of the Portuguese army.

According to the magistrate Guido Salvini, in charge of the investigations concerning the 1969 Piazza Fontana bombing, "Guido Giannettini had contacts with Yves Guérin-Sérac in Portugal ever since 1964."

Aginter Press
It was within this context that he erected Aginter Press in 1965 as a secret anti-communist army with the support of both the PIDE and the U.S. Central Intelligence Agency. Aginter Press set up training camps in which it instructed mercenaries and terrorists in a three-week course in covert action techniques including hands-on bomb terrorism, silent assassination, subversion techniques, clandestine communication and infiltration and colonial warfare." Italian neofascist Stefano Delle Chiaie also participated in the founding of Aginter Press. "During this period, disclosed Guérin-Sérac, we have systematically established close contacts with like-minded groups emerging in Italy, Belgium, Germany, Spain and Portugal, for the purpose of forming the kernel of a truly Western League of Struggle against Marxism." On 31 January 1968, Guérin-Sérac met Pino Rauti, then leader of Ordine Nuovo (he would join again the Italian Social Movement (MSI) the next year. In the 1970s he was in contact with Leo Negrelli, former chief press attaché in the Italian Social Republic.
