Internment
Internment is the imprisonment or confinement of people, commonly in large groups, without trial. Collins English dictionary adds that the term is especially used for the confinement "of enemy citizens in wartime or of terrorism suspects". Thus, while it can simply mean imprisonment, it tends to refer to preventive confinement, rather than confinement after having been convicted of some crime. Use of these terms is subject to debate and political sensitivities.
Interned persons may be held at prisons or at facilities known as internment camps. In certain contexts, these may also be known either officially or pejoratively, as concentration camps.
Internment also refers to the practice of neutral countries in time of war in detaining belligerent armed forces and equipment in their territories under the Hague Convention of 1907.
The Universal Declaration of Human Rights restricts the use of internment. Article 9 states that "No one shall be subjected to arbitrary arrest, detention or exile."
