At least ten people, including five students, are dead after a FedEx truck crossed a divider on a Northern California freeway and slammed into a bus carrying a group of high school seniors who were on their way to tour a college campus.

According to the AP, the bus was full of a group of Los Angeles-area high school seniors headed to Humboldt State University in Arcata, California for a campus tour.

California Highway Patrol told KTLA that a southbound FedEx truck crossed the center divider and crashed head on into the bus. A Nissan Altima was also involved in the crash.

The vehicles collided on the Interstate 5 around 5:40 pm, sparking a fire that completely engulfed the bus. Authorities say several students were airlifted to area hospitals.

UPDATE 8:01 am: The death toll from the crash now stands at 10, including five students. Three adult chaperones, the driver of the bus, and the driver of the truck were also killed.
