A statement by Iraq’s Defense Ministry said the Russian-made Mi-17 utility helicopter crashed in the early hours of Sunday during a training exercise in the central Wasit Province.
The statement added that the cause of the accident was not immediately known.
Iraqi air force officers were separately quoted by Reuters as saying that two pilots and five army officers had been on board the army helicopter and had been killed in the incident.
They cited technical malfunction as the cause of the crash.
Iraqi army helicopters have played an effective role in the fight against Daesh, supporting forces on the ground in their push to drive the Daesh terrorist group out of occupied Iraqi territory.
