Authorities say one child has died and at least four others were injured when a dump truck collided with a school bus carrying elementary school students in a small southwest Idaho city. Emergency crews are responding to the scene today in Kuna, a town about 30 minutes from Boise. Canyon County Sheriff spokeswoman Theresa Baker says as many as 10 children in the sixth grade or younger were on a bus destined for Crimson Point Elementary School. Baker says the dump truck hit the back of the school bus at an intersection, but it's not yet clear who was at fault. (More bus accident stories.)
