UNGWAN GATA/ABUJA Nigeria (Reuters) - When Fulani raiders carrying rifles, machetes and clubs stormed his village one night last month, Pius Nna was stunned to see his teenage nephew among them.
"He was leading them and telling them to check very well, because my house would have a lot of people in it and they would be sure to find someone to kill," said Nna, a tall farmer in his mid-60s who said he escaped by fleeing into the bush.
