WAAY in Huntsville, Alabama.

BIRMINGHAM, Alabama (AP) – Hispanic students have started vanishing from Alabama public schools in the wake of a court ruling that upheld the state's tough new law cracking down on illegal immigration.

Education officials say scores of immigrant families have withdrawn their children from classes or kept them home this week, afraid that sending the kids to school would draw attention from authorities.

There are no precise statewide numbers. But several districts with large immigrant enrollments — from small towns to large urban districts — reported a sudden exodus of children from Hispanic families, some of whom told officials they would leave the state to avoid trouble with the law, which requires schools to check students' immigration status.

The anxiety has become so intense that the superintendent in one of the state's largest cities, Huntsville, went on a Spanish-language television show Thursday to try to calm worried parents.
