WEST PALM BEACH, Fla. — New surface-to-air missile systems have been deployed in Palm Beach as part of expanded security around President Donald Trump, with air defense assets visible near Donald J. Trump International Airport and Mar-a-Lago.

The North American Aerospace Defense Command has said the deployment was made at the request of the U.S. Secret Service.

Gov. Ron DeSantis visited the scene Sunday and described the crash as "cataclysmic," saying the aircraft appeared "like a missile going down" and left a large crater along Military Trail. He praised Palm Beach County first responders for their quick response.

Officials said they had not received reports at the time of the news conference of people on the ground being killed or injured by the crash or debris. DeSantis said the debris field stretched a significant distance.

Palm Beach County officials said approximately 600 people in a nearby mobile home community are expected to be relocated because the crash site is considered a crime scene while authorities investigate. Officials said two shelters were on standby and Palm Tran was prepared to transport residents once law enforcement allowed the evacuation to begin.
