US Secretary of Defense Ash Carter has reportedly revealed that a US Army Apache attack helicopter has carried out a strike against ISIS in Iraq.
The helicopter was used for the first time in an Iraqi combat mission after US President Barack Obama its use in combat operations earlier this year, Reuters reported.
The move comes in response to a request from the Iraqi government for helicopter gunships.
The Associated Press quoted Carter as saying that the strike aimed to retake land in the city of Mosul, which is currently controlled by ISIS.
Mosul has been the ISIS capital in the country since 2014, Stars and Stripes reported.
During the combat sortie, two Apache helicopters flew together but only one of them attacked a target on the ground in northern Iraq, according to Reuters.
The number of ISIS fighters killed in the attack was not disclosed.
Apache helicopters are capable of flying close to the ground at low speeds, allowing forces to easily find and attack targets.
The support from US Army Apache helicopters in Iraq's fight against the militant group demonstrates the increasing involvement of US forces against ISIS in Iraq and Syria.
The US-led coalition is also set to receive new military technology and 450 troops to support the fight.
