US Secretary of State John Kerry will meet Saudi Foreign Minister Saud al-Faisal on Sunday to "update" him on the nuclear negotiations between Iran and six world powers in Vienna, a US official said.
The official did not give details about the meeting. Iran and Saudi Arabia, a close US ally which is worried about the implications of any rapprochement between Washington and Tehran, are regional rivals vying for influence in the Middle East.
