Seven people, including four children, are dead after a tractor-trailer collided with a minivan in upstate New York on Wednesday.

According to an Associated Press report, a tractor-trailer was traveling on a Truxton, New York road just outside of Cortland at around 6 pm Wednesday evening. The semi’s cargo of crushed cars became disconnected from its trailer, causing the trailer to cross the roadway and hit a minivan.

The minivan was reportedly carrying two families. Four children and three adults in the minivan died in the accident, while one man survived and is currently receiving treatment at Upstate University Hospital in Syracuse. The two passengers in the semi were not injured.

One of the two families in the minivan was reportedly from Truxton, a small town of around 1,100 people. The crash occurred on Route 13, a rural, two-lane road that passes through Truxton and serves at the town’s Main Street.
