Further talks to be held next weekend after 'positive' meeting in Muscat, according to top Iranian diplomat, who says US wants to reach a new agreement 'as soon as possible'

Iran and the U.S. held "productive" talks in Oman on Saturday and agreed to reconvene next week, Tehran said, a dialogue meant to address Tehran's escalating nuclear programme with President Donald Trump threatening military action if there is no deal.

President Donald Trump says that Israel would be the “leader” of a potential military strike against Iran if Tehran doesn’t give up its nuclear weapons program.
