Practice Relating to Rule 24. Removal of Civilians and Civilian Objects from the Vicinity of Military Objectives
Ukraine’s IHL Manual (2004) states:
Civilian persons and civilian objects shall be removed from the locations of military objectives. To that end commanders (commanding officers) shall take all measures to interact with local authorities.
Removal of civilians from areas located near military objectives shall be performed to safe areas known to them.
If circumstances permit, effective warning of the defensive actions affecting the civilian population shall be made in advance (e.g. for evacuation of persons from certain buildings or areas).
