"Yemen is full of child brides. Roughly half of Yemeni girls are married before 18, some as young as eight." Until recently, Yemeni law set the minimum age for marriage at 15. But tribal customs and interpretations of Islam often trump the law. In practice, "Yemeni law allows girls of any age to wed, but it forbids sex with them until the indefinite time they’re 'suitable for sexual intercourse.'" In 1999, the minimum marriage age of fifteen for women was abolished; the onset of puberty, interpreted by conservatives to be at the age of nine, was set as a requirement for consummation of marriage.
