A French sailor who was kidnapped from a tanker in Togo has been been freed in southern Nigeria after an army rescue, the military said on Tuesday. \"The man is a Frenchman and he was abducted from a vessel, MT Adour, which was anchored in Togo before the pirates struck,\" military spokesman Lieutenant Colonel Onyema Nwachukwu told AFP, adding that he was not sure of the date of the kidnapping. Soldiers \"invaded the kidnappers\' camp and rescued him last night. No one was arrested as the criminals had abandoned the camp on learning of the (soldiers\') approach.\"
