A four-wheel drive vehicle believed to be carrying 27 people collided with a semi-trailer in Southern California, killing 15 and wounding others, hospital officials said.
Judy Cruz, director of the emergency department at El Centro Regional Medical Center, said 14 people died at the scene and another died after arriving.
Officials believe there were 27 people in an SUV that collided with a tractor trailer full of gravel. Many patients have been hospitalized due to their injuries.
It was not immediately clear what caused the accident.
The accident occurred in the southeastern agricultural corner of California on a highway running through fields in the Holtville area about 100 miles (160.93 kilometers) east of San Diego.
