A Boeing 737 commercial jet with 136 people on board has slid into the St John's River near Jacksonville, Florida after landing, a spokesman for Naval Air Station Jacksonville says, but no fatalities have been reported.
The flight arriving from Naval Station Guantanamo Bay went into the river at the end of the runway at about 9:40pm (local time), the air station said.
Local station WOKV-TV said at least two people suffered minor injuries and the plane was attempting to land during a heavy thunderstorm.
Emergency response personnel were quickly on the scene. US President Donald Trump had also called to offer help.
The mayor of Jacksonville, Lenny Curry, said on Twitter everyone on board was "alive and accounted for" but crews were working to control jet fuel on the water.
"The plane was not submerged. Every person is alive and accounted for," the Jacksonville Sheriff's Office said on Twitter.
The sheriff's tweet was accompanied by photographs showing the plane bearing the logo of Miami Air International resting in shallow water and intact.
Miami Air International is a charter airline operating a fleet of Boeing 737-800 aircraft. Airline representatives could not immediately be reached for comment, while a Boeing spokesman said that the company was aware of the incident and was gathering information.
