Practice Relating to Rule 14. Proportionality in Attack
Burundi’s Regulations on International Humanitarian Law (2007) states: “The utilization of methods and means of combat may not be excessive in relation to the direct and concrete military advantage anticipated.” 
Burundi, Règlement n° 98 sur le droit international humanitaire, Ministère de la Défense Nationale et des Anciens Combattants, Projet “Moralisation” (BDI/B-05), August 2007, Part I bis, p. 81; see also Part I bis, p. 33.
The Regulations also states:
It is prohibited to cause suffering and destruction which are excessive in relation to the aim of the mission. The means utilized must be proportionate to the objective sought. Thus, bombarding a village because a single sniper is located there violates the principle of proportionality.

The Regulations further states: “The rule of proportionality must be respected. … The rule of proportionality does not justify unlimited destruction or attacks against civilians or civilian objects as such.”
