Talks in Vienna aimed at bringing Washington back into the 2015 nuclear deal with Iran are moving ahead with experts working on drafting proposals this week, Russia's delegate said Monday, while adding a solution remains "far away."

"Summing up the results of 2 weeks of deliberations on #JCPOA restoration we can note with satisfaction that the negotiations entered the drafting stage. Practical solutions are still far away, but we have moved from general words to agreeing on specific steps towards the goal," Russian representative Mikhail Ulyanov tweeted.
