Practice Relating to Rule 7. The Principle of Distinction between Civilian Objects and Military Objectives
Section C. Attacks against civilian objects in general
The Report on the Practice of Rwanda considers the prohibition on targeting civilian objects as a required precaution in attack. 
Report on the Practice of Rwanda, 1997, Chapter 1.6.
In situations of armed conflict, while the primary responsibility of the protection of civilians rests with the State, we equally remind non-State actors and the United Nations, including peacekeepers and other humanitarian actors, to prioritize the protection of civilians. Rwanda therefore calls upon the parties to fully observe strict compliance with international law, to avoid targeting civilian objects, to stop militarizing camps and to allow access to humanitarian assistance.
