Practice Relating to Rule 36. Demilitarized Zones
Section B. Attacks on demilitarized zones
Argentina’s Law of War Manual (1989) prohibits attacks on demilitarized zones by any means whatsoever and states that the prohibition of such attacks subsists only as long as such zones comply with the conditions set out in Article 60 of the 1977 Additional Protocol I.
The manual further qualifies attacks against demilitarized zones as grave breaches of IHL.
