None of the released hostages talked about torture or rape. Some were thankful to their captors, for little things like being provided with religious material for praying or being well treated in general. Some of the female hostages complained about being forced to do house chores, but no mass rapes or sexual abuse was reported by them.
Ironically enough, an Israeli hostage was raped in Israel after being freed by the resistance, by her personal trainer.
