 Indefinite detention of an individual occurs frequently in wartime under the laws of war.This has been applied notably by the United States after the September 11, 2001 attacks.Before the Combatant Status Review Tribunals, created for reviewing the status of the Guantanamo detainees, the United States has argued that it is engaged in a legally recognizable armed conflict to which the laws of war apply, and that it therefore may hold captured al Qaeda and Taliban operatives throughout the duration of that conflict, without granting them a criminal trial.
