The Nigerian Maritime Administration and Safety Agency (NIMASA) said on September 23 that seven of those abducted were from the Philippines and one from each of the other five countries.

The 12 workers were still missing. Kidnapping for ransom is a common problem in parts of Nigeria.

A number of foreigners have been kidnapped in the last few years in the southern Niger Delta region, source of most of the oil that is the mainstay of the West African state's economy.
