Between 1960 and 1966, France conducted 17 nuclear tests in the Algerian Sahara. More than half a century later, the waste is still there, and the question of the consequences of these tests remains unanswered. This is stated in a forum of representatives of the Armaments Observatory and ICAN France (the international campaign to abolish nuclear weapons). They call on France to address this crucial issue for the health of the people, for the environment and for relations between Algeria and France. Patrice Bouveret is the director of the Armaments Observatory and co-author of this column, published in the newspaper Le Monde.
