The alleged visit comes two days after the US announced deployment of an aircraft carrier strike group and bomber task force to the Middle East under the pretext of confronting the "Iranian threat."
The summit has marked a shift in Iraq's foreign policy, with the country assuming the role of a mediator in the region as US President Donald Trump has revived the Obama-era concept of an anti-Iranian alliance of Gulf nations.
In January, Mike Pompeo, while finalizing his Middle East tour, in a speech in Cairo noted that the US was working on building a new Middle Eastern alliance led by Washington.
