MIAMI - Miami-Dade police say a 13-year-old girl has died after she was shot by another student on a school bus.
A male student is in custody and police spokesman Alvaro Zabaleta says investigators are talking to him. A gun was also recovered at the scene.
It's not clear what prompted Tuesday morning's shooting in Homestead, south of Miami.
There were about eight other students of a charter school on the bus, including the victim's 7-year-old sister. None of the other children were injured.
The bus driver and the students have been taken to the police station to be interviewed.
Concerned parents gathered at the scene, which was cordoned off by crime scene tape.
Grief counselors were on their way to the charter school.
