VATICAN CITY (Reuters) - Workers have discovered human bones at the Holy See Embassy to Italy and police are investigating the matter, the Vatican said on Tuesday.

Italian media said forensic scientists were looking to see if the remains might be those of Emanuela Orlandi, the 15-year-old daughter of a Vatican employee who vanished in 1983.
