Former UN staffer speaks out about sex abuse scandals

Our guest is Célhia de Lavarène, a French journalist who worked for many years at the United Nations, taking part in a total of seven UN missions. She has now written a book that should soon be published in English, "The stars have deserted the sky". Célhia de Lavarène recounts her role in fighting sexual trafficking while at the UN - a bitter experience, since she felt the top hierarchy at UN headquarters actually turned a blind eye to sexual abuse, in particular by peacekeepers.
