Practice Relating to Rule 36. Demilitarized Zones
Section B. Attacks on demilitarized zones
New Zealand’s Military Manual (1992) states:
Any material breach of [the conditions for a zone to be established as a demilitarized zone] releases the other Party from its obligations under the agreement and the zone loses its special status. It shall, however, continue to enjoy the normal protection provided by the customary and treaty law of armed conflict. 
New Zealand, Interim Law of Armed Conflict Manual, DM 112, New Zealand Defence Force, Headquarters, Directorate of Legal Services, Wellington, November 1992, § 412(5).
The manual further states that “making … demilitarized zones the object of attack” constitutes a grave breach of the 1977 Additional Protocol I.
