Iran, 6 powers move closer to nuke talks deal

Diplomats say Iran and the United States have tentatively agreed that Tehran will ship to Russia much of the material it could use to manufacture nuclear weapons. The two diplomats also say that negotiators at the nuclear talks in December were for the first time able to draw up a catalog that outlines areas of potential accord and differing approaches to remaining disputes. Differences still dominate ahead of the next round of Iran-six power talks on Jan. 15 in Geneva.
