Muscat: US Secretary of State John Kerry will today seek a breakthrough in nuclear talks with Iran, with domestic pressures in both countries now weighing heavily on hopes for a deal.
Kerry will meet Iran's Foreign Minister Mohammad Javad Zarif in Muscat, Oman, seeking to close substantial gaps that in recent months have blocked efforts to turn an interim agreement into a comprehensive settlement.
The meeting follows the revelation that US President Barack Obama reportedly wrote to Iran's supreme leader Ayatollah Ali Khamenei recently to push for a nuclear deal, arguing that the Islamic republic and the West have shared regional interests.
The apparent reference to the fight against Islamic State group militants in Syria and Iraq, however, was played down by Kerry in Beijing on Saturday, with the US diplomat saying "there is no linkage whatsoever" between the nuclear talks and other issues.
With a November 24 deadline for a final agreement just over two weeks away, Iran and the P5+1 group of world powers (Britain, China, France, Russia and the United States plus Germany) are far apart on what capabilities Iran's nuclear programme should have.
The West has as yet been unconvinced by Iran's denials that it has never sought a nuclear weapon -- Tehran insists its atomic activities are for peaceful, civilian energy purposes only. A deal, for the West, aims to put an atomic bomb forever beyond reach.
At issue is the number of uranium-enriching centrifuges Iran should be allowed to keep spinning in exchange for sanctions relief and a transparent inspections regime at its nuclear sites. Iran wants "industrial grade enrichment" beyond its current capabilities while the West wants a reduction.
However, domestic politics now hang heavily over the talks, given the loss in midterm elections of the Senate by Obama's Democrats to the Republican party, members of whom have consistently bridled at the White House's negotiations with Iran.
