Practice Relating to Rule 72. Poison and Poisoned Weapons
In an article published in a military review, a member of the Kuwaiti armed forces stated that, during war, belligerents must:
respect restrictions and limits provided for in international conventions, such as restriction of the use of some weapons, and prohibition of using others, e.g. … the use of poisons. This is in application of well-established principles in wars, such as considerations of military honour and humanitarian considerations.
