Report from Nigeria that the rioting is politically directed sectarian mass murder. The Muslims resent that the Christian Obasanjo won't go. The killing is with machete and stones and petrol, just like the Rwanda tales. The killing is widespread north and east. Obasanjio's authorities cannot control the killing or the fear, and as many as ten thousand are in hiding from marauders.
Meanwhile MEND has cut production from the Niger Delta by 20%. And there is no answer. Without Nigeria light sweet crude, the world demand is on a dire diet.
