Two students killed after school bus 'rolls off motorway overpass'
Two students are dead and three other people are seriously injured after a school bus rolled off a Houston freeway overpass.
A Houston Independent School District statement says a girl died at the scene, and another student died later at a hospital.
The district says two other students and the bus driver were also taken to hospitals with serious injuries.
The bus was bound for Furr High School, which also operates a charter school. The names of the victims have not been released.
Officials are investigating the cause of the crash. District spokeswoman Ashley Anthony says the bus apparently drove off an overpass. Guard rails were damaged. The bus rolled and landed on its side.
Houston operates the state's largest public school district with about 215,000 students.
