Iran has sought support from Russia over a possible deal with Washington over Tehran’s rapidly advancing nuclear program, ahead of a second round of talks this weekend in Rome.

The 2015 nuclear deal collapsed with Trump's unilateral withdrawal in 2018, while Iran abandoned all limits on its nuclear activities and enriches uranium to up to 60% purity, near the weapons-grade levels of 90%.

Iran believes reaching an agreement on its nuclear programme with the United States is possible as long as Washington is realistic, Foreign Minister Abbas Araqchi said on Friday on the eve of a second round of talks with the Trump administration.
