12-year-old girl dies while giving birth

An 11 year old is not a woman. It's a child.

And yes this does have something to do with Islam. It also has something to do with a lack of education, culture, misogyny, and a myriad of other issues.

Being a 12 yr old played a large role in the outcome of her pregnancy. To disregard that is to ignore her psychological state (which can and will cause psychosomatic issues, and other issues with ability to carry to term), her ability to properly care for herself, etc.
