Practice Relating to Rule 120. Accommodation for Children Deprived of Their Liberty
Argentina’s Law of War Manual (1969) provides:
During internment, members of the same family, and in particular parents and children, shall be held in the same place of internment …
Internees can request that their children, left at liberty without the supervision of their parents, shall be interned with them.
As much as possible, interned members of the same family shall be accommodated in the same place, and shall be housed separately from the other internees. They shall be afforded the necessary facilities for leading a normal family life.
