Multiple injuries reported after school bus and dump truck collide on New Jersey highway

Multiple people are injured after a school bus full of children and a dump truck collided on a New Jersey highway on Thursday, authorities said.

Patients have been brought to the nearby Hackettstown Medical Center, but the amount and extent of the injuries are still unclear, Hackettstown Police Sgt. Darren Tynan told Northjersey.com.

The New Jersey state police said on Twitter they were investigating a "serious" collision on Route 80 in Mount Olive Township, but added that no further information was available.

A spokesperson at the Morristown Medical Center also told NBC New York the facility was receiving patients, but didn't yet know how many.

The mayor of Mount Olive, Rob Greenbaum, told Northjersey.com he was watching the rescue efforts from a nearby overpass, and said it was a "horrific scene" and the bus was "mangled."
