ATHENS (Reuter) - A Greek priest and a nun were sentenced to five years each in prison on charges of torturing a teenaged nun while trying to exorcise her, court officials said. They said Father Ephrem and Sister Malamatenia had repeatedly beaten the 16-year old nun with a cane during her three years in a monastery in the northern Serres district. The girl died December 1993 of pneumonia but the coroners` report also said that her body was covered in bruises. Witnesses told the court the two clerics would lock up the girl naked inside a small room during the winter and beat her with the cane. The clerics said in their defence that the girl suffered from psychological problems and that the injuries were self-inflicted.
