BERLIN (AP) — Nascent talks aimed at bringing the United States back into the 2015 nuclear deal with Iran have broken without any immediate signs of progress on the thorny issues dividing Washington and Tehran. But delegates talked on Friday of a constructive atmosphere and resolved to continue the discussions. Two working groups that have been meeting in Vienna since Tuesday to brainstorm ways to secure the lifting of American sanctions and Iran’s return to compliance with the deal reported their initial progress to a joint commission of diplomats from the world powers that remain in the deal. Russian delegate Mikhail Ulyanov tweeted that participants had “noted with satisfaction the initial progress made.”
