Conflict in the Niger Delta
The current conflict in the Niger Delta first arose in the early 1990s over tensions between foreign oil corporations and a number of the Niger Delta's minority ethnic groups who feel they are being exploited, particularly the Ogoni and the Ijaw. Ethnic and political unrest continued throughout the 1990s despite the return to democracy and the election of the Obasanjo government in 1999. Struggle for oil wealth has fueled violence between ethnic groups, causing the militarization of nearly the entire region by ethnic militia groups, Nigerian military and police forces, notably the Nigerian Mobile Police. The violence has contributed to Nigeria's ongoing energy supply crisis by discouraging foreign investment in new power generation plants in the region.
