Disputes linger as U.S. and European negotiators work with Iran to solidify an accord to curb Iran's nuclear program. Jillian Kitchener reports.
(SOUNDBITE) (English) U.S. SECRETARY OF STATE JOHN KERRY, SAYING: "Well I think it's fair to say that we are hopeful. We have a lot of hard work to do. There are some very tough issues." Disagreements remain between top U.S., European and Iranian diplomats... as they hammer out a deal to curb Iran's nuclear program. But talks in Vienna must go on, as a self-imposed June 30 deadline looms. French Foreign Minister Laurent Fabius says Western powers want a robust deal that recognizes Iran's right to civilian nuclear power, yet guarantees Iran give up any nuclear weapons capability. (SOUNDBITE) (French) FRENCH FOREIGN MINISTER, LAURENT FABIUS, SAYING: "For this, we think there are at least three essential conditions: the first is a lasting limit on Iran's research and development capacity. The second condition is a rigorous inspection of sites, including military if needed, and the third condition is the automatic return of sanctions if it violates its commitments. These three conditions respect Iran's sovereignty." Tehran insists its nuclear program is for peaceful purposes only. And Iranian Foreign Minister, Mohammad Javad Zarif, is pressing for sanctions on his country to be removed immediately. But the pace and timing of sanctions relief are among the biggest sticking points in the talks. U.S. and European negotiators also want to ensure there is a mechanism for restoring those sanctions if Tehran fails to meet its end of the bargain.
