The Saudi government on Monday said it hopes a nuclear deal between Iran and world powers can bolster Middle East peace and end interference in Arab affairs.

A statement after the weekly cabinet meeting chaired by King Salman said Saudi Arabia "hopes the agreement will reinforce security and stability in the region and the world".

But it insisted security hinged on "the respect of the principle of good neighbourly relations and non-interference in Arab affairs," said the Saudi Press Agency.

The statement was issued on the 12th day of Saudi-led air strikes against Shiite rebels in Yemen who Riyadh says are backed by Iran.

A framework agreement aimed at curbing Iran's suspect nuclear programme was clinched on Thursday after marathon talks in Switzerland.

King Salman said after the deal was announced that he was looking forward to a "final binding" agreement that would bolster regional and world security.

Iran and Saudi Arabia, the foremost Shiite and Sunni Muslim powers in the Middle East, have had troubled relations in recent years.

Riyadh says Iran is trying to expand its influence across war-hit Syria, Shiite-majority Iraq and in Lebanon.

Obama vows to address Iran's 'destabilizing' role in Mideast
Washington (AFP) April 6, 2015 - President Obama on Monday said he would continue to work with US partners to address Iran's "destabilizing activities" in the Middle East, even as details of a nuclear deal with Tehran are thrashed out.

During a phone call with Sultan Qaboos, Obama pledged to work "with Oman and other regional partners to address Iran's destabilizing activities in the region," the White House said.

Obama's call was part of a drive to convince skeptical allies that a tentative deal over Iran's nuclear program does not signify a softening of US opposition to Iran's role in the region.

Arab states accuse Iran of fueling a series of proxy battles in the Middle East that have destabilized Syria, Iraq, Yemen, Lebanon and other states.

Obama has invited leaders of the several Gulf states to Camp David in the near future in a bid to assuage their concerns.
