Transportation officials say at least 22 people were killed when a bus collided with a car, sending them both plunging 230 feet down a mountainside in Bolivia.

Police Comm. Luis Herbas says the bus was traveling from Cochabamba to the Bolivian capital of La Paz when the wreck took place. Another 28 travelers were injured in the crash and were being treated at a nearby hospital.

A family of five was traveling in the car. A father and his daughter died.

The collision took place before dawn on Wednesday.
