Iran nuclear negotiations open in Vienna as deadline for deal on sanctions looms on July 20.

Iran and the United States traded warnings of the consequences of failure yesterday as negotiators arrived in Vienna for a final round of nuclear talks aimed at securing a historic deal by a July 20 deadline.
We’re hopeful that we can make progress in narrowing those gaps and pursuing that comprehensive solution but the Iranian side is going to have to take additional steps that it should be able to take,” Ben Rhodes, the US deputy national security adviser, said. “This has been a top priority for our administration.”
