Actually we don't know yet if it's the religion or some tribal law. If this happened in a Christian country, there would be some kind of punishment for the tribal leaders, we'll see what happens to them since it's a Muslim country instead.
Quite right. It's not difficult to guess what will happen in this Islamic country. I find it appalling that there those here who are pointing at Christian conquests and inquisitions instead of condemning this disgraceful instance of ill-treatment of women!
