The last execution by guillotine in France was in 1977.
Hamida Djandoubi was a Tunisian immigrant who had been convicted of the torture and murder of 21-year-old Elisabeth Bousquet in Marseille. Likely a moslem, I’d say.
Quote from the Judge who recorded an account of Djandoubi’s execution: “He called the Imam who came over and spoke to him in Arabic. He responded with a few words, also in Arabic.”
