State Department: No progress in Iran nuclear talks

The so-called P5+1 nations unveiled the new proposal at the end of the last bout of talks, in February. It's considered more generous than past proposals and would  allow Iran to keep open its uranium enrichment plant at Fordo and retain a small amount of enriched uranium that Iran says it needs for medical research. 

Iranian negotiator Saeed Jalili welcomed the proposal at the time, calling it “more realistic” and “closer to the ... proposal presented by Iran.” On Friday, however, Iranians failed to directly respond to the proposal but instead put forth previous talking points that left U.S. diplomats “puzzled,” according to The Washington Post.
