Iran's nuclear deal with world powers Tuesday will make the Middle East a "more dangerous part of the world" if it comes with too many concessions, a Saudi official said, signaling gulf Arabs' deep unease over the accord.
The Saudis and their gulf allies fear that the deal, by ending Iran's pariah status and freeing its economy from crippling sanctions, will embolden Tehran to step up its backing for their foes across the Middle East.
Saudi authorities offered only terse public comment on the Vienna deal, some 10 hours after it was announced, but officials privately made clear their misgivings about its likely impact in a region where the Sunni Muslim kingdom has long competed with Shiite Iran for influence.
