in international law the compulsory detention of foreign citizens by warring or neutral states during a time of armed conflict. Internees are settled in a defined locality which they are forbidden to leave. Internment of foreign civilians is distinguished from the internment of foreign military personnel.
Internment applies mainly in relation to civilians of one of the warring sides in permanent or temporary residence on the territory of the other warring side. Military personnel falling into the hands of the enemy are not internees but prisoners of war. Internment of enemy troops can take place only during an armistice, when military action and consequently the taking of prisoners cease.
Also subject to internment are military personnel of the warring sides arriving on the territory of a neutral state. Interned military personnel are disarmed and subjected to restrictions to prevent them from leaving the territory of the neutral state and resuming military activities. The neutral state supplies the internees with food and clothing and extends other services to them, which gives it the right to compensation after the end of hostilities.
Questions of internment were regulated by various clauses of the Geneva Convention of 1929. The Geneva Convention of 1949—Protection of the Civilian Population in Time of War— regulates in detail the status of foreign citizens and specifies that the place of internment must be outside the zone of military activities and, when possible, be designated by special markings. Internees are supported free of cost by the warring sides (they are supplied with such essentials as food, clothing, and medical help), and they have the right to correspond with relatives and with appropriate international organizations.
During World War II, fascist Germany brutally flouted the norms of international law on internment (for example, with regard to the right of asylum). Also in violation of international law was the internment by Anglo-American occupation authorities of Soviet citizens who had been forcibly transported by the Hitlerites to Germany and other European countries.
