Parties to Iran Nuclear Deal to Meet on Sunday, EU Says

PARIS - Parties negotiating a revival of the Iran nuclear deal will hold a formal meeting in Vienna on Sunday, the European Union said Saturday.

Iran and six world powers have been negotiating in Vienna since April to work out steps for Washington and Tehran to take. The United States withdrew in 2018 from the pact, under which Iran accepted curbs on its nuclear program in exchange for a lifting of many foreign sanctions against it. Sunday's formal meeting comes more than a week after this round of talks resumed and is an indication that the talks are likely to be adjourned. Officials over the week have indicated that differences remain on key issues.
