"In the coming days, we will carry out a number of attacks against installations and oil companies across the Niger Delta and will spread out to companies such as Total which have been spared in the past," the group said in an email to AFP.
The Movement for Emancipation of the Niger Delta called off a three-month unilateral truce in January following an anger with the Nigerian government for lack of progress in the implementation of a post-amnesty programme for former fighters in the region.
