Attacks by bands of Ijaw men on other tribes have left some fifty people dead. The Ijaw claim to be the largest tribe in the Niger delta oil region, and say that they are not getting their fair share of benefits from the oil production. Actually, few locals got much benefit from the oil operations. Most of the profits were stolen by government officials. For years, most of that money went to Moslems officials from the north. But now, less of the money is being stolen, and what is taken is going more to corrupt Christian officials from the south. But the tribes in the delta have become more militant in demanding a share of the wealth. The cutting edge of this has been gangs of young men who also engage in stealing oil (by tapping into pipelines), smuggling and other scams.
