Clutching an assault rifle, Ekai Lokipeng shows off six marks on his chest, the result of ritual scarification ceremonies to indicate the number of people he has killed. The scars symbolise the pride that Kenyan pastoralists along the country's volatile border with Ethiopia take in protecting their herds from rustlers. But they are also a source of despair for Lokipeng who has grown tired of decades of constant cross-border raids and deadly inter-clan violence, reports the Mail and Guardian.
