The Wall Street Journal reported that the administration of US President Donald Trump is pressuring Saudi Arabia and the United Arab Emirates to stop the embargo they are imposing on Qatar Airways flights in their airspace.

The newspaper said that Trump pressed personally - in a telephone conversation with King Salman and Crown Prince Mohammed bin Salman - to end the air embargo that compels planes flying to Doha, in most cases, to fly over Iran, a move that gives Tehran a source of funding that the United States wants to cut.

According to the Wall Street Journal, the Trump administration has put aside comprehensive mediation efforts to end all aspects of the dispute as a result of repeated diplomatic setbacks, and instead focuses - instead - on solving one component - the issue of airspace.

The newspaper said that the money received by Iran because of what is known as "flying overhead fees", has become unexpected side effects of the decision of the four countries to boycott Qatar.
