Practice Relating to Rule 35. Hospital and Safety Zones and Neutralized Zones
Sierra Leone’s Instructor Manual (2007) states:
Protected Areas
Safety Zones
These are battle-free zones set aside for the protection of wounded and sick and vulnerable citizens (elderly, children, mothers).
Neutralised Zones
These are battle-free zones created by agreement between the parties to the conflict to protect the wounded and sick (both combatants hors de combat and civilians) and civilians who are not performing any work of a military nature.
