Nigerian gunmen 'kidnap 4 foreign oil workers'

Gunmen attacked a barge belonging to an oil services company off the coast of Nigeria on Saturday, kidnapping four foreigners and killing two Nigerian sailors, the navy said. "Four expatriates are reported to have been kidnapped from the vessel. Two sailors were killed," navy spokesman Commodore Kabir Aliyu said, adding that the nationality of those abducted had yet to be ascertained. Six naval personnel -- all Nigerians -- were aboard the vessel, which belongs to the Sea Truck oil services company, for security. Two were killed and two were wounded, he said. The Nigerian navy has dispatched a boat and a helicopter to the area, he added.
