Difficulties at the Iran nuclear negotiations in Vienna are rooted in the West's stance on lifting the arms embargo against Iran, an Iranian source said.
"In particular, the United States voiced its opposition to removing the arms embargo… This is one of the main conditions for reaching an agreement," RIA Novosti cited the source as saying. The source added that Russia and China spoke in favor of lifting the weapons sanctions, while the rest were in the US camp.
Another Iranian source said that the consultations had been extended after Western negotiators toughened their position, they were also having trouble coordinating stances among themselves.
