Kidnapped ‘Chibok girl’ returns after five months in captivity. Spends initial night of freedom screaming ‘They will kill me!’ ... Some 276 female students were abducted by Nigeria's Islamic militant Boko Haram fighters from the Government Secondary School where they had gathered to write final examinations in the early hours of April 15. Fifty-seven escaped by themselves that night or the following day - some by jumping from the open-backed trucks that transported them and clinging to branches of low-hanging trees.
