A senior American official on Monday said that the US was extremely dissatisfied with Oman's mediation in the talks with Iran and declined to use Muscat's services. The aforesaid official spoke about this, commenting on the online signing of a memorandum of understanding between Tehran and Washington aimed at ceasing hostilities.

"We were very unhappy with the job the Omanis did. We felt they were very duplicitous and almost like employees of the Iranians in the way that they maneuvered, so we kind of threw them out of this process," the American official said during a special telephone press briefing.
