Operation North Night Final was a joint DR Congo-UN peacekeeper operation in December 2005 to restore peace in the troubled Ituri district in DR Congo. The operation was mainly aimed at fighting the Ugandan rebels stationed there (Allied Democratic Forces/National Army for the Liberation of Uganda) and involved ca. 3,500 Congolese troops, supported by 600 UN peacekeepers using helicopter gunships.
