While not all actions leading to civilian casualties breach international humanitarian law, UNSMIL reminds all parties to the conflict that they are under an obligation to target only military objectives. Direct attacks on civilians as well as indiscriminate attacks – which do not distinguish between civilians and fighters – are prohibited.
Attacks that are expected to cause incidental loss of civilian life, injury to civilians and damage to civilian objects excessive to the anticipated concrete and direct military advantage are also prohibited. Such attacks amount to war crimes that can be prosecuted by the International Criminal Court.
In order to ensure greater protection of the civilian population and essential infrastructure, all parties engaged in fighting in Libya must cease the use of mortars and other indirect weapons and imprecise aerial bombardments in civilian-populated areas, and not place fighters or other military objectives in populated areas.
All executions of captives must cease and all those captured including fighters must be treated humanely in all circumstances. Murdering or torturing captives is also a war crime, regardless of what the captive may be accused of.
