IHL contains specific legal provisions and criteria determining situations to which it applies, as well as the extent of the personal, temporal and geographical scopes of application. To determine whether IHL applies to any given situation, an objective assessment has to be conducted in line with those legal provisions and criteria, based on facts on the ground in the circumstances prevailing at the time.
