Part III : Captivity #Section II : Prisoners of war camps - Art. 9.
Art. 9. Prisoners of war may be interned in a town, fortress or other place, and may be required not to go beyond certain fixed limits. They may also be interned in fenced camps; they shall not be confined or imprisoned except as a measure indispensable for safety or health, and only so long as circumstances exist which necessitate such a measure.
Prisoners captured in districts which are unhealthy or whose climate is deleterious to persons coming from temperate climates shall be removed as soon as possible to a more favourable climate.
Belligerents shall as far as possible avoid bringing together in the same camp prisoners of different races or nationalities.
No prisoner may at any time be sent to an area where he would be exposed to the fire of the fighting zone, or be employed to render by his presence certain points or areas immune from bombardment.
