NBC News: A student and adult chaperone are dead and many injuries have been reported after a full-size school bus collided with a dump truck on a major New Jersey highway Thursday morning.

A student and adult chaperone are dead after a full-size school bus collided with a dump truck on a major New Jersey highway Thursday, a violent accident that ripped the undercarriage completely off the bus and left it demolished on its side in the median, according to NBC New York.

Many injuries have been reported. An unknown number of middle school students were on board the school bus at the time of the 10:20 a.m. crash on Route 80 near exit 25 in Mount Olive Township, according to the New Jersey State Police.

No additional details on the children or the nature of the injuries were available. Morristown Medical Center confirmed it was receiving patients but a spokesperson did not know how many were expected to arrive at the hospital.

Photos obtained by NBC New York shows the heavily damaged bus on its side in the median, surrounded by dozens of emergency and law enforcement vehicles. The front of it is barely recognizable, a mangled chunk of broken-apart machinery spread from the highway shoulder lane through the guardrail and into the grassy median, where police and first responders are seen tending to stunned children. The undercarriage, the bus wheels still attached, lays perpendicular to the overturned bus, stretching out over multiple lanes of the highway.
