A statement purporting to come from the Movement for the Emancipation of the Niger Delta said yesterday that it received USD 2-million ransom for the sailors, mostly from Nigerian authorities.
US officials identified the mariners as the captain and chief engineer of the US-flagged C-Retriever offshore supply vessel taken in a Wednesday attack.
Analysts believe the militant group has lost much of its operational capability, but oil pipeline attacks and kidnappings are still common in the Niger Delta.
