(Reuters) – Some of the schoolgirls abducted by militant group Boko Haram may never return home, Nigeria’s influential former president Olusegun Obasanjo said, in some of the most pessimistic comments yet on their fate from a member of the country’s elite. Obasanjo said President Goodluck Jonathan’s administration had taken too long to respond to the April mass abduction. Once Jonathan’s mentor and one of his strongest political allies, Obasanjo turned against him last December. “I believe that some of them will never return. We will still be hearing about them many years from now,” Obasanjo told the BBC’s Hausa-language radio service on Thursday, in comments echoed in an interview with Nigeria’s Premium Times website.
