Two US Army Black Hawk helicopters collided mid-air over Kentucky on Thursday resulting in the death of at least nine soldiers in the crash.
The incident took place during a routine training mission over the state.
The status of the crew members was not immediately known, the U.S. Army’s Fort Campbell said in a statement, without providing the number of people who were on board.
“We’ve got some tough news out of Fort Campbell, with early reports of a helicopter crash, and fatalities are expected,” governor Andy Beshear said in a post on Twitter, adding that local authorities and emergency services were responding to the accident.
Crew members were flying two HH-60 Black Hawk helicopters, operated by the 101st Airborne Division, which crashed at around 10:00 p.m. ET (0200 GMT Thursday) in Kentucky’s Trigg County, Fort Campbell’s public affairs office said.
“The command is currently focused on caring for the service members and their families,” the statement said, adding that the cause of the crash was under investigation.
