A woman flew from Istanbul to Paris with an infant girl hidden inside her hand luggage, Air France has said. An airport source told AFP news agency that the woman was a resident of France who was in the process of adopting the child, from Haiti. It is not clear how old the child was - one source said she was four years old, another that it was a one- or two-year-old baby. The woman and the girl have been held at Charles de Gaulle airport while authorities investigate the case.
