Iranian Foreign Minister Mohammad Javad Zarif tweeted on Thursday that "an agreeable solution is possible" for the United Nations (UN) nuclear watchdog's request for access to two nuclear sites in the country. 

France, Britain and Germany, all parties to Iran's 2015 nuclear deal with major powers, have submitted a draft resolution to the International Atomic Energy Agency's (IAEA) Board of Governors calling on Iran to stop denying the agency access to two old sites and to cooperate fully with it, diplomats taking part in an IAEA virtual meeting said.

"BoG (IAEA's Board of Governors) should not allow JCPOA (Joint Comprehensive Plan of Action) enemies to jeopardize Iran's supreme interests. E3 (France, Britain and Germany) should not be an accessory, after failing own JCPOA duties," Zarif tweeted. "We've nothing to hide. More inspections in Iran over last 5 yrs than in IAEA history. An agreeable solution is possible, but Res will ruin it." 

The Joint Comprehensive Plan of Action, or JCPOA, is the official name of Iran's multilateral nuclear deal. The United States withdrew from the deal in May 2018.

If the IAEA resolution is passed, it would raise pressure on Iran to let inspectors into the two sites where the IAEA suspects activities potentially related to developing nuclear weapons were carried out in the early 2000s, long before the deal.

The UN nuclear watchdog's governing body began meeting on Monday as a row brews over Iran's refusal to allow access to the two sites. The IAEA expressed "serious concern" in a report earlier this month that Iran has been blocking inspections at the sites. 

Iran said the report was a source of "deep regret and disappointment" and hinted the queries were based on "fabricated information" from "intelligence services." 

In a statement to the Board of Governors opening this week's meeting, IAEA Director General Rafael Grossi called on Iran "to cooperate immediately and fully with the Agency, including by providing prompt access to the locations specified by us."
