St. John’s, Nfld. resident Bob Croke was among 19 people released after a military operation in Nigeria Wednesday. The oil worker was taken hostage on Nov. 8 from the Okoro oil field, which is 11 km off the coast of Akwa Ibom state in the Atlantic Ocean. Foreign Minister Lawrence Cannon confirmed the release, but a Foreign Affairs spokeswoman told CTV News they would not provide further details. “That might compromise or jeopardize the safe return of someone else in the future,” she said. Bombings and kidnappings of foreigners are common in oil-rich but poverty-heavy West Africa.
