A US grandmother climbed to the top of a crane in France on Saturday to protest against being prevented from seeing her granddaughter, whose father is accused of sexually assaulting the girl. The stunt was the latest in a series of separated parents scaling cranes across France to complain about lack of access to their children. April Reiss, 70, said a French court had ordered the girl's Belgian mother to let her see her during a two-week period but that she was refusing to comply.
