There is "radiological and chemical contamination" within Iran's Natanz facility, International Atomic Energy Agency Director-General Rafael Grossi told the United Nations Security Council Friday.

"It is possible that uranium isotopes contained in uranium hexafluoride, and hydrogen fluoride, are dispersed inside the facility," Grossi said.

Grossi said there is destruction at multiple sites including Natanz, Isfahan and Arak as well as sites in Tehran, but there are no sites where radiological activity has been identified outside facilities.

Grossi warned that the Bushehr nuclear facility might be hit, saying that this would be, "the nuclear site in Iran where the consequences of an attack could be most serious. It is an operating nuclear power plant and as such it hosts thousands of kilograms of nuclear material."

Worst case scenarios of an attack on Bushehr "would necessitate protective actions such as evacuations and sheltering of the population or the need to take stable iodine with a reach extending to distances from a few to several hundred kilometres," Grossi said.

European leaders are meeting with Iranian diplomats in Geneva on Friday, attempting to reach a diplomatic resolution that would prevent Iran from developing its nuclear weapons program.

"No one should deny the risk of Iran getting a nuclear weapon," French President Emmanuel Macron said Friday. "It’s a real risk. We have never denied this."

Macron also said that any agreement would have to ensure that the International Atomic Energy Agency could restart its work to achieve "zero enrichment" in Iran and that Iran's ballistic missile program and its financing of "terror groups" in the region should also be part of the negotiation.

There was no reason to launch an Israeli operation against Iran, Russian Foreign Ministry spokeswoman Maria Zakharova said in comments Friday.

The Iranian nuclear program should not be the subject of aggressive actions, but the subject of negotiations, Zakharova added.

In response to a question about Israeli Prime Minister Benjamin Netanyahu's comments that the Iranian leader could become a target of Israeli attacks, Russian President Vladimir Putin said, "I would like such things to remain at the level of rhetoric. Russia has always stood for ensuring the security of every country without compromising the security of another."

Russia and China are not forming a new world order, but they are "shaping it," Putin said in comments at the St. Petersburg International Economic Forum (SPIEF) on Friday.

"The new world order is emerging naturally -- it's like the sun rising, there's no escaping it," Putin added.
