Iran’s Deputy Foreign Minister Sayed Abbas Araghchi on Sunday ruled out any direct or indirect talks with the US one day before heading to Vienna for much-anticipated talks on reviving the 2015 nuclear deal.

Axar.az reports that Araghchi told reporters that there is only "one step", which is Washington lifting sanctions "imposed, re-imposed and relabeled" over the years.

"Our main condition is that the United States first fulfills all its obligations and removes all sanctions, and then we verify them and return to full compliance," Araghchi said, terming the Vienna talks as "purely technical."
