Practice Relating to Rule 12. Definition of Indiscriminate Attacks
Section A. Attacks which are not directed at a specific military objective
Prior to the adoption in 1992 of UN General Assembly Resolution 47/37 on the protection of the environment in times of armed conflict, Jordan and the United States submitted a memorandum to the Sixth Committee of the UN General Assembly entitled “International Law Providing Protection to the Environment in Times of Armed Conflict”. The memorandum stated:
It is a war crime to employ acts of violence not directed at specific military objectives, to employ a method or means of combat which cannot be directed at a specific military objective, or to employ a means or method of combat the effects of which cannot be limited as required by the law of armed conflict. 
Jordan and United States, International Law Providing Protection to the Environment in Times of Armed Conflict, annexed to Letter dated 28 September 1992 to the Chairman of the Sixth Committee of the UN General Assembly, UN Doc. A/C.6/47/3, 28 September 1992, § 1(g).
The Report on the Practice of Jordan cites as an example of indiscriminate attacks those which are not directed at a specific military objective.
