A 12-year-old girl bled to death three days after a 'swap marriage' here in Yemen's northern province, a report has said.

Child bride Ilham Mahdi Shui al-Asi died last week of severe internal bleeding from a ruptured womb, which caused a fatal haemorrage. She was married for just three days to a man in his 20s in what is known as a 'swap' marriage in the region, the report said Thursday.
