WorldToxic Colonisation: How France Waged Secret Chemical Warfare in Algeria

The documentary examines claims that the French army secretly used chemical weapons during Algeria’s war of independence, in defiance of international law. It presents archival material and testimony from former French soldiers and Algerian fighters. The film frames the conduct as a French violation of the 1925 Geneva Protocol. Historian Christophe Lafaye cites a 1956 letter from a senior army commander to the government referring to the “use of chemical means.”
