New Jersey Gov. Phil Murphy says the crash of a dump truck and a school bus taking children to a field trip has killed a student and an adult.

Authorities say 45 people were on a school bus that collided with a dump truck on a New Jersey highway, killing a student and a teacher.

The yellow school bus was carrying 38 students and seven adults Thursday when it crashed, leaving it on the median of Interstate 80 in Mount Olive with its front end shattered.

A boy who was on the bus says the bus fell over and people were left "hanging from their seat belts."

The school bus was left on the median with its front end crushed or ripped off. A red dump truck with a mangled front end was parked along the highway nearby.

The Paramus school district says the bus was taking students from East Brook Middle School to Waterloo Village, a historic site near the crash scene.

Governor Murphy says his heart is "broken."

Waterloo Village is a historic site depicting a Lenape Indian community and once-thriving port along the Morris Canal in northwestern New Jersey. It features several historic homes, a blacksmith shop, general store and more. It's a popular spot for school trips.

"I have never seen anything like that. I can only describe it as horrific," Mayor Robert Greenbaum said. "It doesn't take long to look at this accident scene and to understand how horrific the injuries would be."
