"France has no more hostages, in any part of the world."Hollande's office said in a statement Lazarevic, described by authorities as an engineer, was in "relatively good health despite the very trying conditions of his long captivity".On Tuesday evening Lazarevic had reached Niger's capital Niamey, where he met president Mahamadou Issoufou.
