Europeans doubt Iran's intentions in nuclear talks

France, Britain and Germany on Saturday said they had "serious doubts" about Iran's intentions to revive a nuclear deal, comments that were rejected by Tehran and called "very untimely" by Moscow.

Iran earlier this month sent its latest response to the European Union's proposed text to restore the 2015 agreement under which Tehran had restrained its nuclear programme in exchange for relief from U.S., EU and U.N. economic sanctions.

Diplomats have said Iran's response to the EU coordinator was a step backwards, with it seeking to link a revival of the deal with the closure of investigations by the International Atomic Energy Agency (IAEA) into uranium traces at three sites.
