ROUGH CUT (NO REPORTER NARRATION) STORY: U.S. President Barack Obama tells CBS Face the Nation that there is "still a big gap" on Iran nuclear talks, and that "we may not be able to get there." He also made it clear that there is no link or trade off between Iran and the U.S. on the nuclear issue in terms of the broader U.S. policy. "We do have a shared enemy in ISIL, but I have been very clear publicly, and privately, we are not connecting in any way the nuclear negotiations from the issue of ISIL," he said. Senior envoys of Iran, the United States and European Union met in Oman on Sunday to tackle stumbling blocks in efforts to defuse the standoff over Tehran's nuclear program. Reiterating Iran's official line, Ali Akbar Velayati, a top aide to Supreme Leader Ayatollah Ali Khamenei, was quoted by Iranian media as saying the Islamic Republic would not abandon its nuclear "rights" but was committed to the negotiations under Khamenei's leadership. Western countries and close U.S. ally Israel suspect Iran has covertly sought to develop the means to build nuclear weapons, and a decade-long confrontation over the issue has raised the risk of a wider war in the volatile Middle East. The discussions, between Iranian Foreign Minister Mohammad Javad Zarif, U.S. Secretary of State John Kerry and EU envoy Catherine Ashton, aim to put verifiable limits on Iran's uranium enrichment work - and any other potential path to a nuclear weapon - in return for a gradual lifting of sanctions.
