A US military helicopter, HH-60 Pave Hawk helicopter, has crashed in western Iraq with seven personnel on board, US officials said.
The officials further said the Pave Hawk was carrying seven personnel, but was not on a combat mission.
They said that so far there is no indication that the helicopter was shot down near the border with Syria.
The helicopter is used by the Air Force for combat search and rescue, and was in transit from one location to another when it went down Thursday afternoon near the town of Qaim in Anbar Province.
US officials said that rescuers were responding to the location, but other details were not yet available.
It's not clear if there were any survivors, reports AP.
The officials spoke on condition of anonymity to discuss details of the crash before it was made public.
US Central Command said that "rescue teams are responding to the scene of the downed aircraft at this time," adding that an investigation will be started to determine the cause of the incident.
The US-led coalition battling Islamic State insurgents in Iraq and Syria have an outpost in Qaim, which is located near the Syrian border.
The anti-IS campaign accelerated through much of last year, as coalition and Iraq forces battled to take back a string of cities and towns.
