France says insults in the Iranian media against first lady Carla Bruni-Sarkozy, who has been branded an “Italian prostitute” who “deserves death”, are unacceptable.The insults in the daily Kayhan and picked up by Iranian websites against several French figures, including Mrs Carla Bruni-Sarkozy, are unacceptable, Foreign Ministry spokesman Bernard Valero said.The Iranian press reacted with fury last week after Ms Bruni, the wife of French President Nicolas Sarkozy, made a public statement in support of an Iranian woman who has been sentenced to be stoned to death. She and other French personalities signed a petition calling for Teheran to release 43-year-old mother-of-two Sakineh Mohammadi-Ashtiani, whom an Iranian court has convicted of adultery and complicity in her husband's murder.The case has triggered an international outcry, and the French government has made a formal protest and threatened sanctions.
