Iran has proposed meeting the European parties to a 2015 nuclear deal possibly in Rome this Friday if talks resume with the United States, four diplomats said on Monday, cautioning that there has yet to be a response from the Europeans to the idea.

Iran and the United States held in-depth negotiations in Oman over Tehran's rapidly advancing nuclear program Saturday, ending the discussions with a promise for more talks and perhaps another high-level meeting next weekend.
