US Iran rep says Tehran must let inspectors into nuke site The U.S. special representative for Iran says that the Islamic Republic must “immediately” give international inspectors access to two sites that harbor traces of nuclear material or activity

PARIS -- The U.S. special representative for Iran said Thursday the Islamic Republic must "immediately" ensure inspectors have access to sites that harbor traces of nuclear material or activity.

The finding was made public in a report this week by the international nuclear watchdog, which said Iran is denying access.

In one of two confidential reports, the International Atomic Energy Agency identified three locations where Iran possibly stored undeclared nuclear material or conducted activities without declaring them to international observers. The Associated Press saw the report to member countries. The other report said Iran nearly tripled its stockpile of enriched uranium since November, violating a deal with world powers.

The IAEA said its request for access to two of the sites was denied, although the nuclear-related activities are thought to date from the early 2000s.

The spokesman for Iran's nuclear agency, Behrouz Kamalvandi, responded Wednesday that requests for access must have a legal basis, according to Iran's semi-official ISNA news agency. He didn't elaborate.

The U.S. official, Brian Hook, said the access is required under the Nuclear Non-Proliferation treaty to which Iran is a signatory, meaning it must provide access “immediately.”

"Iran must be held to the same standards as every one of the other 190 parties" to the treaty, he said during a meeting with a group of reporters.

Hook was in Paris to meet his French, German and British counterparts, signatories of the 2015 nuclear deal with Iran that the Trump administration pulled out of in 2018. The U.S. wants a more inclusive deal that addresses ballistic missiles and Iran's regional ambitions in Syria and elsewhere. Instead, Washington has levied punishing economic sanctions on Iran as part of its "maximum pressure" campaign against Iran.

While noting the three European nations have "tactical disagreements" with the United States, he stressed their common concern that Iran not obtain nuclear arms.

China and Russia also are signatories to the deal, the Joint Comprehensive Plan of Action, which promised Iran economic incentives in return for curbs on its nuclear program. Those incentives have failed to materialize, along with European efforts to create a mechanism allowing Iran to get around U.S. sanctions that has yet to get off the ground. Iran, in turn, has incrementally violated the deal's restrictions with measures it maintains are reversible in what it says is a "maximum resistance" campaign.

Hook stressed special concern about a step written into the nuclear deal — the lifting of a U.N. arms embargo and other sanctions in October. He claimed the deal is a way station on a path to allowing Iran to have nuclear weapons once restrictions on centrifuges are lifted in 11 years.

In what appears to be a bid to buy time to negotiate, the European signatories have invoked a dispute resolution mechanism that is part of the deal. It ultimately could lead to reintroducing sanctions, known as "snapback," but that is not said to be their goal.

Hook appeared, for now at least, to put to rest any speculation that the U.S. could try to step back into the deal, claiming participation despite the pullout, to trigger the snapback.

"We're out of the deal," he said when asked, "and so the countries that are in the deal will make decisions that are in their sovereign capacity."
