"Six are dead, 20 walking wounded, 9 serious injuries," said Joe Cobb, spokesman with the Atlanta Police Department.

The bus was carrying a baseball team from Bluffton University in Ohio. It fell off an exit bridge onto the southbound lanes of Interstate 75 - a major highway - near downtown Atlanta and TV images showed the shattered wreck lying on its side.

Cobb told Fox News the cause of the crash was not immediately clear.
