The fast-track trial of a Moroccan immigrant accused of stabbing his 18-year-old daughter to death last year in an 'honour' killing opened in the northeastern Italian town of Pordenone on Monday. El Ketaoui Dafani, a cook, allegedly became enraged after discovering his daughter Sanaa had a love affair with a 32-year-old Italian man. Sanaa Dafani was stabbed in the throat in September with a large kitchen knife while she was sitting in a car with her 31-year-old boyfriend in the small town of Montereale Valcellina, northwest of Trieste.
