Practice Relating to Rule 70. Weapons of a Nature to Cause Superfluous Injury or Unnecessary Suffering
Madagascar’s Military Manual (1994) states: “Weapons causing unnecessary suffering shall not be used.” 
Madagascar, Le Droit des Conflits Armés, Ministère des Forces Armées, August 1994, Fiche No. 6-O, § 13.
In 1975, during discussions in the Ad Hoc Committee on Conventional Weapons established by the CDDH, Madagascar stated in relation to the report of the Conference of Government Experts on the Use of Certain Conventional Weapons that Might Cause Unnecessary Suffering or Have Indiscriminate Effects: “Those provisions … were inadequate, for they reaffirmed rules that were already to be found in other international instruments.”
