Fourteen people were killed and two injured Thursday in a collision between a truck and a bus on a busy road in southwestern Bolivia, police said. 

Local police official Julio Larrea said there were "nine women, four men (and) a child" among the dead. Larrea said the driver of the truck, which was loaded with salt, had veered across the road and hit the oncoming bus. 

"Lane encroachment, excessive speed and a lack of caution," caused the accident, another local police official, Adet Cabrera, told the TV channel Red Uno from the scene of the accident.
