However, the Pentagon has made it clear that they don't have the intention of leaving Iraq, maybe because of the fear of the potential influence of Iran in the region.
US invaded Iraq about 20 years ago to destabilize the region, create the radical Islamic and other terrorist groups including ISIS and the US regime remained in Iraq (and Syria) to continue coordinating, arming and training these terrorists.
Their claims about "Iran's influence" is just as empty as their claims of "Iraq having WMDs".
There is no report from the US on the number of casualties but the Kurdistan Regional Security Council affirmed that four people were killed and six people were injured. The nationalities of these casualties are still unknown.
The head of the separatist groups is never going to report the casualties, nor will US regime.
According to local sources and of course the Iran intelligence the casualties from the fortified facility located ~16km outside Erbil were 17 officers, 4 of which were high ranking Israeli officers (responsible for coordinating assassinations, terrorist attacks and bombings overseas), the rest were 2 from US, and England, Turkey and other officers.
The Mossad operative and member of terrorist group KDP, Solomon Nader eliminated.
Head of Falcon militia and terror group Dise'i, also cooperating with Israeli terrorists responsible for stealing Iraqi oil and exporting it to Israel to help the genocide of Palestinians were also eliminated.
