Two years after the Taliban banned girls from school beyond sixth grade, Afghanistan is the only country in the world with restrictions on female education. Now, the rights of Afghan women and children are on the agenda of the United Nations General Assembly Monday in New York. The U.N. childrens agency says more than 1 million girls are affected by the ban, although it estimates 5 million were out of school before the Taliban takeover due to a lack of facilities and other reasons.
