- US troops are part of a multinational coalition fighting ISIS in Iraq and Syria
- Early reports indicate that the deaths were not due to enemy contact, the military said
"Initial reports indicate the incident was not due to enemy contact," the statement said. The incident is under investigation.
The troops were part of the US- led coalition that has been fighting against ISIS in Iraq since 2014. They were not immediately identified.
Coalition commander Lt. Gen. Stephen Townsend issued a statement offering condolences to the families, friends and comrades of the service members.
"The entire counter-ISIS Coalition sends our deepest condolences to these heroes' families, friends and teammates." He added that he hoped "there is some small solace in knowing their loss has meaning for our country and all the nations of the Coalition as the fallen service members were fighting to defeat a truly evil enemy and to protect our homelands."
On Monday Pentagon spokesman US Army Col. Robert Manning stated: "An Army artillery section was conducting a counter fire mission against an ISIS mortar site when a mishap occurred injuring seven soldiers. There is no indication that ISIS had anything to do with this. The injured soldiers were air-evaced and two of the soldiers subsequently died, the other 5 soldiers did not suffer life threatening injuries."
Manning went on to add that an investigation into the incident is ongoing.
Close to 5,000 US troops are currently aiding in the fight against ISIS.
A month after Iraq's Prime Minister Haider Al Abadi declared victory over ISIS in Mosul, the coalition continues to aid the Iraqi armed forces fight against ISIS in other towns throughout the country.
Within Iraq, the coalition's main focus is to liberate the towns of Tal Afar, Hawija and the town of Al Qaim in the Euphrates River valley.
The coalition is also working to liberate Raqqa, ISIS' de-facto capital in Syria.
