A tour bus carrying South Carolina students home from a field trip has crashed on a mountain road just across the North Carolina border, sending 15 people to hospitals with minor injuries.

WYFF-TV reports the bus crashed Friday afternoon, injuring three adults and 12 children ages 8 to 14. An aerial view showed the bus ran off the road and into some trees.

Authorities said the injuries were not life threatening.

Richland County district 2 spokeswoman Theresa Riley said the bus was carrying students from Blythewood Middle home from YMCA Camp Greenville in Cedar Mountain, N.C. She says school officials have notified the families of students taken to hospitals.

Another bus will transport the uninjured students back to the Columbia area Friday night.
