High-level ministerial talks between Iran and the P5+1 world powers over the Persian nation's nuclear activities have ended without a preliminary agreement in which the country would curb its program in a return for an easing of sanctions. France objected that the proposals didn't do enough to limit Iran's program.
Of particular concern is a heavy-water reactor that Iran has been building in Arak and which would produce plutonium.
However, the sides believe they've made enough progress to hold another round and they'll go at it again in ten days, although not at the ministerial level.
Analysts had said that oil prices could plunge if an agreement were to have been reached this weekend, as seemed possible on Friday.
