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.
The warning came as militants and the army exchanged fire after a government helicopter gunship attacked barges allegedly used by smugglers to transport stolen crude oil.
Correspondents say the militants provide security for the smugglers.
Nigeria is Africa's leading oil exporter and the fifth-biggest source of US oil imports, but despite its oil wealth, many Nigerians live in abject poverty.
Aims
It is the first time the military leader of the Mend movement, Major-General Godswill Tamuno, has spoken publicly of his group's aims.
