AlHijjah 16, 1433, Nov 1, 2012, SPA - Kidnappers freed six Russian sailors and an Estonian on Wednesday who had been abducted from a ship off Nigeria's southern delta, a French oil and gas services company said. Paris-based Bourbon SA said in a statement that the sailors were in good health despite facing "difficult conditions while in captivity." The company said the men would leave Nigeria in several days after undergoing medical tests and psychological examinations, according to a report of the Associated Press.
