Marathon talks between Iran and major powers towards a historic nuclear deal ran into the early hours Tuesday as signs emerged that an agreement might be imminent. Foreign ministers of the six powers (P5+1) were expected to hold a potentially final meeting Tuesday morning ahead of a planned announcement that would bring to a close an 18 day marathon push to strike an accord. The White House said on Monday that the marathon discussions in Vienna had “made genuine progress”. “But there continues to be some sticking points that remain unresolved,” White House spokesman Josh Earnest told reporters in Washington. He said the United States and it’s partners did not want to rush the final stages of the lengthy talks. “Typically, some of the most difficult issues are the ones that get kicked to the end and that’s why the president is going to resist any effort to sort of fast forward through the closing here,” Earnest said. If a deal can be sewn up, the prospect of a subsequent possible thawing of US-Iranian relations unsettles many in the Middle East, however. These include Shiite Iran’s Sunni rivals Saudi Arabia and other Gulf monarchies who see Tehran as a destabilising influence in the region. Israel is also deeply concerned, complaining that the proposed deal will fail to stop it’s arch fore getting the bomb.
