Practice Relating to Rule 10. Civilian Objects’ Loss of Protection from Attack
Section A. Civilian objects used for military purposes
Burundi’s Regulations on International Humanitarian Law (2007) states: “A civilian object may become a military objective for reasons of military necessity. This is, [for example], the case with a bridge, which is a civilian object but may become a military objective if it is used by the adversary.”
