Oromo Liberation Front (OLF) fighters patrol an area of bush near the Kenyan border, in their ?4th Military Zone?. The area is dangerous and the fighters need to keep a look-out for both Ethiopian government forces and Kenyan border patrols. Kadjila (front) is 27, and was once in the Ethiopian army but defected to join the OLF. .The OLF have been fighting a ?forgotten war? against successive Ethiopian governments since the 1970s. Their aim is independence for Oromia and its 30 million strong Oromo community.
