Practice Relating to Rule 85. The Use of Incendiary Weapons against Combatants
Section A. The use of incendiary weapons in general
In 1973, in response to Resolution 2932 A (XXVII) in which the UN General Assembly asked States to comment on the report of the UN Secretary-General on napalm and other incendiary weapons and all aspects of their possible use, Iran stated:
Given a general consensus within the international community to take action on these weapons, the Government of Iran would think that the most practical approach would be to consider a prohibition on the use of all incendiary weapons.
