Alabama police in standoff with kidnapper

In Alabama, authorities have helicopters, armored vehicles and teams standing by to rescue a six-year-old boy who is being held hostage in a bunker.

The child was kidnapped from his school bus. The kidnapper allegedly boarded the bus and demanded the driver hand over one of the children. When they refused, the suspect shot and killed the driver, and grabbed one of the children before fleeing the scene.

They have been holed up in an underground bunker for three days.
