12-year-old girl dies while giving birth

Sorry I disagree....

A dad forcing a 11 year old girl to marry a old man...is different than a girl chooses to have sex or drink....

The difference is choice and consent. In the case of the Yemeni girl, she had no choice and an adult made the decision to marry her off and then another adult got her pregnant at the age of 11 and she died as a consequence of those actions.
