A Nigerian militant commander in the oil-rich southern Niger Delta has told the BBC his group is declaring "total war" on all foreign oil interests. The Movement for the Emancipation of the Niger Delta has given oil companies and their employees until midnight on Friday night to leave the region. It recently blew up two oil pipelines, held four foreign oil workers hostage and sabotaged two major oilfields. The group wants greater control of the oil wealth produced on their land. It is the first time the military leader of the Mend movement, Major-General Godswill Tamuno, has spoken publicly of his group's aims. He refused to be interviewed on tape or for his location to be disclosed. He told the BBC's Abdullahi Kaura Abubakar that they had launched their campaign, called "dark February", to ensure that all foreign oil interests left. He said that they had had enough of the exploitation of their resources and wanted to take total control of the area to get their fair share of the wealth.
