Among those taken were eight crew members of a German-owned ship, confirmed Hamburg-based company MC-Schiffahrt in a statement on its website on Friday, adding that it had assembled an emergency team and was cooperating with local authorities in the West African country to deal with the incident.

The sailors were aboard a vessel in the Gulf of Guinea when the pirates attacked them. The specific number and nationality of those who have been kidnapped are still unknown.
