Mexican officials say a bus on a school field trip has crashed in the western state of Michoacan, killing 11 people, including three children.

State prosecutor's office spokesman Jonathan Arredondo says another 34 people were injured Wednesday when the bus crashed into a house and then split in half. He says the brakes may have failed.

Arredondo says the bus was traveling to an exotic animal farm with kindergarten students, parents and teachers aboard when the accident occurred in the small town of San Marcos.

The school had rented the bus for the day.
