US Secretary of State John Kerry said Monday the US would not let Iran acquire nuclear weapons.
Kerry was speaking in Riyadh at a joint news conference with Saudi Foreign Minister Prince Saud al-Faisal after talks with King Abdullah.
Kerry reiterated that the United States was determined Iran would not get a nuclear weapon and promised to keep Saudi leaders abreast of any talks with Tehran, saying there would be "no surprises". Iran says it is enriching uranium only for civilian energy purposes.
Saudi concerns are partly founded on a fear that President Barack Obama's moves to reduce tensions with Iran will give Riyadh's main regional adversary an opportunity to extend its influence in Arab countries.
