France, Britain and Germany on Saturday vented their frustration at Iran's demand in talks to revive its 2015 nuclear deal that the U.N. nuclear watchdog close a probe into uranium particles found at three sites, adding that it was jeopardising the talks, Trend reports citing Reuters.
Iran earlier this month sent its latest response to the European Union's proposed text to revive the 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 the uranium traces.
"This latest demand raises serious doubts as to Iran's intentions and commitment to a successful outcome on the JCPoA," the three countries, known as the E3, said in a statement, referring to the deal's full name, the Joint Comprehensive Plan of Action.
