Two US Army helicopters collided on Wednesday while on a training mission over Kentucky.
The status of the crew members was not immediately known, a spokesperson told Reuters.
"We've got some tough news out of Fort Campbell, with early reports of a helicopter crash and fatalities are expected," Kentucky's governor, Andy Beshear, said in a post on Twitter early on Thursday.
We’ve got some tough news out of Fort Campbell, with early reports of a helicopter crash and fatalities are expected. @kystatepolice, @KentuckyEM and local officials are responding. We will share more information as available. Please pray for all those affected.
