Évian Accords
Shortly after the final Gerboise bomb ("Gerboise Verte)," the French moved their nuclear testing to the mountainous In Ekker region, which housed an underground facility. In 1962, the Algerian War ended with the signing of the Évian Accords. Although the French military agreed to withdraw from Algeria within 12 months, Chapter III of the Évian Accords granted France "the use of a number of military airfields, the terrains, sites and installations necessary to her." It was because of this stipulation that France was able to continue nuclear testing in Algeria until 1966.
