Aginter Press, also known under the name Central Order and Tradition (Portuguese: Ordem Central e Tradição), was a pseudo press agency set up in Lisbon, Portugal in September 1966, under Oliveira Salazar's dictatorship (so-called Estado Novo). Directed by Captain Yves Guérin-Sérac, who had taken part in the foundation of the OAS in Madrid, a terrorist group which fought against Algerian independence towards the end of the Algerian War (1954–1962), Aginter Press was in reality an anti-communist mercenary organisation with subsidiaries in other countries. It trained its members in covert action techniques, including bombings, silent assassinations, subversion techniques, clandestine communication and infiltration and counter-insurgency.
Strategy of tension
Aginter Press took part in Italy's strategy of tension, a campaign of false flag bombings and an attempted coup d'état organised by the Italian neo-fascists with support from Propaganda Due (P2) and Gladio, NATO's stay-behind anti-communist networks during the Cold War.
This agency is alleged to have carried out work for various right-wing authoritarian governments (including Salazar, Franquist Spain, the Greek Regime of the Colonels after the 1967 putsch, etc.) Its agents worked under the cover of reporters or photographers, which allowed them to travel freely.
Aginter strategic document
An Aginter Press document, titled "Our Political Activity," was discovered at the end of 1974 and described the use of pseudo-operations
"Our belief is that the first phase of political activity ought to be to create the conditions favouring the installation of chaos in all of the regime's structures. .. In our view the first move we should make is to destroy the structure of the democratic state under the cover of Communist and pro-Chinese activities. .. Moreover, we have people who have infiltrated these groups and obviously we will have to tailor our actions to the ethos of the milieu — propaganda and action of a sort which will seem to have emanated from our Communist adversaries. .. [These operations] will create a feeling of hostility towards those who threaten the peace of each and every nation. [i.e. Communists]" 
Italian Senate report
"Aginter Press was in reality, according to the last obtained documents acquired by the criminal investigation, an information centre directly linked to the CIA and the Portuguese secret service, that specialized in provocative operations." 
The group was headed by Yves Guérin-Sérac, a Catholic anti-communist activist, former officer of the French Armed Forces and veteran of the Indochina War (1945–54), the Korean War (1950–1953) and the Algerian War (1954–1962). The Italian neo-fascist terrorist Stefano Delle Chiaie was another founding member of Aginter Press. Hired in June 1962 by Franco, Yves Guérin-Sérac then chose to go to Salazar's Portugal, which was according to him the last stronghold against Communism and atheism.
Beside Portugal itself, Aginter Press is alleged to have engaged itself against the independentist movements struggling against the Portuguese empire as well as in Italy. It is suspected of having assassinated General Humberto Delgado (1906–1965), founder of the Portuguese National Liberation Front, although this has been disputed since PIDE's officer Rosa Casaco has admitted he was involved in Delgado's assassination. According to disputed sources, Aginter Press is alleged to have been responsible for the assassinations of anti-colonialist leader Amílcar Cabral (1924–1973), founder of the PAIGC (African Party for the Independence of Guinea and Cape Verde) and Eduardo Mondlane, leader of the liberation movement FRELIMO (Frente de Libertação de Moçambique), in 1969. According to other versions, both Cabral's and Mondlane's assassinations were the result of struggles for power within the independentist guerrilla movements.
1969 Piazza Fontana bombing
"In these investigations data has emerged which confirmed the links between Aginter Press, Ordine Nuovo and Avanguardia Nazionale... It has emerged that Guido Giannettini [one of the neo-fascist responsible for the bombing] had contacts with Guérin-Sérac in Portugal ever since 1964. It has emerged that instructors of Aginter Press. .. came to Rome between 1967 and 1968 and instructed the militant members of Avanguardia Nazionale in the use of explosives."
Carnation Revolution: the end
During the April 1974 Carnation Revolution which put an end to Salazar's Estado Novo, Yves Guérin-Sérac, João Da Silva and others associates quit Lisbon for Albufereta, Spanish site of the Paladin Group (founded by ex-Nazi Otto Skorzeny), near Alicante (Southern Spain). They then escaped with forged French passports to Caracas, with the alleged "benediction of the Foccart networks."
