The article also states that the girls have Norwegian schooling and Norwegian papers. The family lived in Norway at the time the middle girls (if not all) were mutilated.
IMO, the family sent girls back to avoid discovery of what they did. The youngest girls may have even been born in Norway and then subjected to the horror in Europe and only saw Gambia so parents didn’t see jail in Norway.
IMHO, proper punishment for the father would be total castration.
No, it says the girls had papers and schooling, it did NOT say that it was done in Norway. I’ve read that a lot of it gets done “at home”, i.e., the origin country, by family. . .
