All nine people aboard a Learjet are killed after it crashes onto a busy road in Palm Beach County, Florida

A business jet carrying nine people plunged into a South Florida neighborhood on Sunday afternoon and exploded near a busy road, killing everyone on board, The Associated Press reported, citing Transportation Secretary Sean Duffy.

The Learjet 60 had left Austin-Bergstrom International Airport in Texas and was headed to North Eleuthera Airport in the Bahamas when it went down near Cresthaven in Palm Beach County at about 12:50 p.m., the Federal Aviation Administration said, according to NBC News. Duffy called it a "horrific tragedy" in a social media post. The names of the people on board have not been released.

Video of the aftermath showed a crater in the middle of the road engulfed in flames, NBC reported. Gov. Ron DeSantis described the crash as "cataclysmic" and said it "looked like a missile going down." He said the crash spewed a large amount of debris, but there were no reports of anyone on the ground being hurt.

The crash happened on Military Trail, a six-lane road lined with businesses and restaurants, the Palm Beach County Sheriff's Office said, according to the BBC. Officials said about 600 residents of a nearby mobile home community were evacuated.

The National Transportation Safety Board is leading the investigation with help from the FAA. The cause of the crash has not been determined.
