A report Tuesday by Iran's semi-official ISNA news agency quotes Hamid Baidinejad, a nuclear negotiator, as saying the two sides had "achieved mutual understanding on implementation (of) the nuclear deal."
The report said Baidinejad said the deal likely will be implemented in late January. State television also quoted senior Iranian nuclear negotiator Abbas Araghchi as saying he may meet again with Helga Schmid, a senior European Union negotiator, next week.
Iran reached a deal with world powers in November to limit its enrichment of uranium and neutralize its stockpile of 20-percent-enriched uranium in exchange for sanctions to be eased.
