  the crews of civil aircraft of the Parties to the conflict, who do not benefit by more favorable
  treatment under any other provisions of international law.
  6. Inhabitants of a non-occupied territory, who on the approach of the enemy spontaneously
  take up arms to resist the invading forces, without having had time to form themselves into

  war.
  B. The following shall likewise be treated as prisoners of war under the present Convention:
  1. Persons belonging, or having belonged, to the armed forces of the occupied country, if the
  occupying Power considers it necessary by reason of such allegiance to intern them, even
  though it has originally liberated them while hostilities were going on outside the territory it
  occupies, in particular where such persons have made an unsuccessful attempt to rejoin the
  armed forces to which they belong and which are engaged in combat, or where they fail to
  comply with a summons made to them with a view to internment.
  2. The persons belonging to one of the categories enumerated in the present Article, who have
  been received by neutral or non-belligerent Powers on their territory and whom these Powers
  are required to intern under international law, without prejudice to any more favorable
  treatment which these Powers may choose to give and with the exception of Articles 8, 10, 15,
  30, fifth paragraph, 58-67, 92, 126 and, where diplomatic relations exist between the Parties
  to the conflict and the neutral or non-belligerent Power concerned, those Articles concerning
  the Protecting Power. Where such diplomatic relations exist, the Parties to a conflict on whom
  these persons depend shall be allowed to perform towards them the functions of a Protecting
  Power as provided in the present Convention, without prejudice to the functions which these
  Parties normally exercise in conformity with diplomatic and consular usage and treaties.
  C. This Article shall in no way affect the status of medical personnel and chaplains as provided
  for in Article 33 of the present Convention.
  ARTICLE 5
  The present Convention shall apply to the persons referred to in Article 4 from the time they fall
  into the power of the enemy and until their final release and repatriation.
  Should any doubt arise as to whether persons, having committed a belligerent act and having
  fallen into the hands of the enemy, belong to any of the categories enumerated in Article 4, such
  persons shall enjoy the protection of the present Convention until such time as their status has
  been determined by a competent tribunal.

  agreements for all matters concerning which they may deem it suitable to make separate
