Practice Relating to Rule 55. Access for Humanitarian Relief to Civilians in Need
Section B. Impediment of humanitarian relief
The Philippine Army Soldier’s Handbook on Human Rights and International Humanitarian Law (2006) provides:
During combat operation:
13. Do not block the entry of food, health services and education to the civilian populace as a way to defeat the enemy. If you plan to neutralize the enemy through this method, the civilian population will surely be affected. However, “government forces may prevent or limit the entry of service workers (eg. DSWD [Department of Social Welfare and Development] personnel) and the delivery of goods into an area of armed conflict if the same will interfere directly with ongoing combat operations, or will endanger the lives or safety of service workers or those delivering the goods. Any dispute arising from the restriction of the flow of goods and services shall be resolved by the Peace and Order Council concerned.”
