At least 16 people have died following US military plane crash in the southern state of Mississippi at around 16:00 local time (21:00 GMT) on Monday, BBC reported.
The crash happened in LeFlore County, about 100 miles (160km) north of Jackson, the state capital.
The victims were on the Marine Corps aircraft and there were no survivors, Leflore County emergency management director Fred Randle said.
Mississippi Governor Phil Bryant said the incident was a “tragedy”.
“Our men and women in uniform risk themselves every day to secure our freedom,” he said.
No official details were immediately available on the circumstances of the crash.
Mississippi outlet the Clarion-Ledger said the plane came down in a soybean field on the Sunflower-Leflore county line, and left a five-mile trail of debris. It said the FBI was assisting at the scene.
