Practice Relating to Rule 35. Hospital and Safety Zones and Neutralized Zones
The Hellenic Navy’s International Law Manual (1995) provides:
In order to safeguard the unimpeded transfer of protected persons to hospital ships, a practice was established during the Falklands war, according to which a certain neutral area was demarcated named “Red Cross Boxes”. This practice, given the increased sensitivity of states regarding the protection of the right to life for non-combatants and persons hors de combat
, tends to rapidly crystallize a customary rule, closely dependent upon the particular conditions under which naval warfare is waged and the vicinity where military operations are conducted.
