All United Nations Security Council resolutions related to Iran's nuclear program will be lifted immediately if a final deal is agreed, Foreign Minister Mohammad Javad Zarif said on Saturday, stressing the benefits to Iran of this week's negotiations.

After leading Iranian negotiators to a preliminary deal with world powers in Switzerland, Zarif must now convince a domestic audience that the talks are heading toward a final deal that is in Iran's interest.

He disputed a "fact sheet" released by the United States shortly after the deal that emphasized Iranian concessions and referred to sanctions being suspended rather than lifted and only after confirmation that Teheran has complied with the terms of the agreement.
