US President Barack Obama discussed regional issues with Saudi King Salman, who expressed hope that a final nuclear deal between Iran and world powers will boost security in the region.

In a phone call with Obama on Thursday, Salman "expressed his hope that a final binding deal would be reached to reinforce the stability and security of the region and the world," the SPA news agency said.

 Obama also said Washington “is committed” to support Saudi’s current aggression on Yemen, the Saudi agency added.

A framework agreement on Iran's nuclear program was clinched Thursday after marathon talks in Switzerland. It marked a major breakthrough in a 12-year standoff between Iran and the West.

Another Gulf nation, Oman, on Friday welcomed the agreement reached in Lausanne as historic.

A statement from the foreign ministry in Muscat said that a final deal, to be reached by June 30, should open "a new era for more regional and international security and stability".

Oman enjoys good relations with Iran, which enabled it to play a key mediating role between the West and Tehran over the nuclear program.
