A 6-year-old Afghan girl sold by her father into an impending marriage to pay off a family medical debt got a reprieve Monday.She will now get to stay with her parents, thanks to an anonymous donor who is paying off the debt of $2,500 through an American lawyer, according to a still-developing New York Times report.The girl, Naghma, wound up being bartered by father Taj Mohammad after he borrowed the $2,500 from a fellow refugee-camp resident over the course of a year.The money was to pay for a hospital treatment for his wife and medical care for some of his nine children, including a three-year-old who later froze to death.If he couldn’t pay it off in another year, Naghma would be forced to wed the lender’s 17-year-old son.“They said, ‘Pay back our money,’ and I didn’t have any money, so I had to give my girl,” Mohammad told the New York Times. “I was thankful to them at the time, so it was my decision, but the elders also demanded that I do this.” Soon after the deal was struck, the boy to whom Naghma was engaged insisted that she stop attending school, which she loves, her father said.On Monday afternoon, there was no word on who paid off the debt or how. But now that it has been paid, said a New York Times follow-up story, the girl, Naghma, will remain with her family. She will no doubt continue to live in extreme poverty in the Kabul refugee camp, and will perhaps even forced into marriage when she’s older. Still, she is one of the luckier girls of Afghanistan, where half of all girls are forced to marry under age 15, according to estimates by the United Nations agency UN Women. That’s despite the legal age for marriage in the country being 16 for girls.Ending the practice remains a huge challenge in Afghanistan's patriarchal society, where it’s somewhat traditional to give girls away to settle debts or pay for their relatives’ crimes. Tribal customs often condone marriage once puberty is reached, or even earlier, and the government has been unable or unwilling to challenge the law effectively.Manizha Naderi, the executive director of Women for Afghan Women, a group that runs various shelters in the country, told the New York Times in a previous article that poverty is the motivation for many child marriages. That’s either because a wealthy husband pays a family well for his bride, or because the father of the bride will then have one less child to support. “Most of the time they are sold,” Ms. Naderi said. “And most of the time it’s a case where the husband is much, much older.”Stories like Naghma’s come at a slow but steady clip out of Afghanistan and many other countries, including India. In 2010, two girls, ages 13 and 14, dressed as boys and fled their elderly husbands after refusing to consummate the marriages. They made it far from their remote village, but were eventually caught by police and returned home, where they were publicly, viciously flogged. Authorities did nothing, despite the flogging being caught on tape and human-rights groups’ efforts to intervene.While the case may have been shocking, Fawzia Kofi, a prominent female member of Parliament, told the New York Times that, it was far from the only one. “I’m sure there are worse cases we don’t even know about,” she said. “Early marriage and forced marriage are the two most common forms of violent behavior against women and girls.”In a more recent and widely reported case, a 15-year-old Afghanistan girl forced into marriage, Sahar Gul, was rescued from six months of torture at the hands of her in-laws. They kept her locked in a basement, ripped out her fingernails and burned her with hot irons—and, a rare instance of justice, were eventually brought to justice and sentenced to 10 years in prison.According to a short Pulitzer Center film, “Too Young to Wed: The Secret World of Child Brides,” by National Geographic photographer Stephanie Sinclair, “Child marriage occurs in more than 50 developing countries around the world, and almost always results in the girl’s removal from school. What families don’t realize,” Sinclair explains through her narration, “is by curtailing a girl’s education, they’re only perpetuating the cycle of poverty.She added, “As one Afghan police officer told me, girls are routinely seen as family burdens, while their male counterparts are seen as kings.”
