A young Turkana warrior arrives with cattle to a settlement in Ilemi Triangle, Kenya, July 20, 2019. The Ilemi Triangle, a disputed sliver of land along the border with Ethiopia and South Sudan, is the northernmost tip of Turkana, Kenya's poorest county. A series of deadly clashes between the Turkana community and other ethnic groups that they said had crossed from South Sudan have put people on edge, to the point of posting lookouts.

As in many regions across Africa, farmers and nomads frequently clash over limited resources, be it land, cattle or water. Cows and bulls are the most important currency here, not cash. When danger looms, locals say the police are usually far away and neighbours are the only ones they can turn to. (Photo by Goran Tomasevic/Reuters)
