Practice Relating to Rule 36. Demilitarized Zones
Section B. Attacks on demilitarized zones
Cameroon’s Instructors’ Manual (1992) mentions the duty to avoid hostilities from the air over demilitarized zones and emphasizes that, while these zones cannot be made the object of an attack, it is also prohibited to launch an attack from a demilitarized zone.
Cameroon’s Instructor’s Manual (2006) states that in air operations “[demilitarized zones] must not be the object of bombardments, nor constitute the basis for launching attacks”.
The manual further states that “an attack against … demilitarized zones” constitutes a grave breach of IHL.
