Practice Relating to Rule 35. Hospital and Safety Zones and Neutralized Zones
Kenya’s LOAC Manual (1997) states:
Hospital and safety zones may be set up in peacetime to contain hospitals, shelters for the wounded and sick, the old and infants, children under 15 years of age, expectant mothers and mothers with children under 7 years of age. Upon the outbreak and during the course of hostilities, the parties concerned may conclude agreements on mutual recognition of the zones and localities they have created.

The manual further states:
As an emergency measure, the commanders of the Parties to the conflict may establish, in the regions where fighting is taking place, neutralized zones intended to shelter from the effects of war the following persons, without distinction:
(a) wounded and sick combatants or non-combatants;
(b) civilian persons who take no part in hostilities and who, while they reside in the zones, perform no work of a military character.
To effect such a zone, a written agreement shall be concluded and signed by the representatives of the Parties to the conflict.
