The Organisation armée secrète ( OAS ) was created in Madrid by French military officers opposed to the independence of Algeria . Many of its members would later join various anti-communist struggles around the world . Some , for example , joined the Cité catholique fundamentalist group and went to Argentina , where they were in contact with the Argentine Armed Forces . Jean Pierre Cherid , former OAS member , took part in the 1976 Montejurra massacre against left-wing Carlists . He was then part of the Spanish GAL death squad , and participated in the 1978 assassination of Argala , one of the ETA members who had killed Franco 's Prime minister , Luis Carrero Blanco , in 1973
