This study revolves around the NATO-led Operation Unified Protector in Libya 2011. The military campaign was executed under a UN mandate to protect the Libyan civilian population. Despite the mandate civilians died because of NATO bombings. The purpose of this study is to identify inadequate measures in avoiding civilian casualties during the operation and to continue to work towards minimizing civilian casualties caused by military organizations in international interventions. Early in the operation, NATO’s objective altered from protecting the civilians to over­throwing the Libyan regime. At the same time NATO changed its military targeting. This study concludes that the alteration of the primary objective to have increased the risk of harming innocent civilians in the area of operation because the protection of civilians became a secondary objective.
