Qatar is the latest Gulf Arab state to welcome the nuclear deal between Iran and world powers, calling it a step toward greater stability in the region.

The Gulf's main political power, Saudi Arabia, has previously expressed unease about U.S. outreach to Iran. The dialogue helped pushed along efforts by Washington and others to strike a deal with Iran seeking to ease Western concerns that Tehran could move toward nuclear weapons.

Saudi officials have withheld public comment on the first-step deal signed on Sunday in Geneva, but smaller Gulf partners have backed the accord.

Qatar's Foreign Ministry said on Monday that the deal is an "important step toward safeguarding peace and stability in the region."

Bahrain, Kuwait and the United Arab Emirates have issued similar statements.
