Members of the Istanbul-based Association For Families With Lost Relatives hand out Thursday flyers with photos of Sarai Sierra, a New York City woman who disappeared while on vacation in Istanbul. Sierra, a 33 year-old mother of two, has been missing since January 21, when she was due to return home. Turkish police have set up a special unit to search for her and are trying to trace a man she had been in contact with during her stay. — AP
