6 Russians, 1 Estonian Kidnapped Off Nigeria Freed

Seven crew members of an anchor handling ship kidnapped last month by attackers who stormed their vessel off Nigeria have been released, French company Bourbon said on Thursday.

Nigeria's military said it played a role in the release of the six Russian and one Estonian sailors although a statement from the Marseilles-based firm gave no details of the circumstances including whether or not a ransom had been paid.

"Despite difficult conditions while in captivity, they all appear to be in good health," Bourbon said, adding that "no information will be given about the demands (or) the context" of the release.

Scores of kidnappings for ransom have occurred in the Niger Delta. A 2009 amnesty deal greatly reduced unrest there, but incidents still occur regularly.

Borboun said that branches of Nigeria's security service, including a Joint Military Task Force (JTF) "worked towards this liberation," but did not elaborate.

Colonel Onyema Nwachukwu, a JTF spokesman, said troops from the unit were involved in securing the release.

"Of course JTF operatives were involved by combing the nooks and crannies of the Niger delta to ensure that the hostages were released unhurt. But we will not comment on ransom or any operational details," he said.

The crew, kidnapped on October 15, were undergoing medical checks in Nigeria and would return to their home countries within the next few days, Bourbon said.

The targeted ship, the Bourbon Liberty 249, was an anchor handling vessel, the kind used to tow anchors for oil rigs or mobile drilling rigs.

In a report earlier this year, the International Maritime Bureau said the Gulf of Guinea was emerging as a new piracy hub, with heavily armed gangs carrying out increasingly violent attacks, where crude theft was often the goal.
