Yemen is ranked last of 135 countries in the 2012 Global Gender Gap Report. Human Rights Watch reported on discrimination and violence against women as well as on the abolition of the minimum marriage age of fifteen for women. The onset of puberty (interpreted by some to be as low as the age of nine) was set as a requirement for marriage instead. Publicity about the case of ten-year-old Yemeni divorcee Nujood Ali brought the child marriage issue to the fore not only in Yemen but also worldwide.
