Russia is telling the United States not to strike Iran because it would radically destabilize the Middle East, Russian Deputy Foreign Minister Sergei Ryabkov said on Wednesday, and Moscow said Israeli strikes risked triggering a nuclear catastrophe.

Russia signed a strategic partnership with Iran in January and also has a relationship with Israel, although it has been strained by Moscow’s war in Ukraine. A Russian offer to mediate in the Israel-Iran conflict has not been taken up.

Ryabkov, speaking on the sidelines of an economic forum in St Petersburg, told Interfax news agency Moscow was urging Washington to refrain from direct involvement.

“This would be a step that would radically destabilize the entire situation,” Interfax cited Ryabkov as saying, and criticizing such “speculative, conjectural options.”

The head of Russia‘s SVR foreign intelligence service, Sergei Naryshkin, has said the situation between Iran and Israel is now critical and Foreign Ministry spokeswoman Maria Zakharova said the Israeli strikes on Iranian nuclear infrastructure meant the world was “millimeters” from catastrophe.

“Nuclear facilities are being struck,” she told Reuters, adding that the UN nuclear safety watchdog had already noted specific damage.

“Where is the [concern from the] entire world community? Where are all the environmentalists? I don’t know if they think they are far away and that this [radiation] wave won’t reach them. Well, let them read what happened at Fukushima,” she said, referring to the 2011 accident at the Japanese nuclear plant.

Israel says it has struck Iranian nuclear facilities to prevent Tehran developing an atomic weapon. Iran denies seeking nuclear arms.

RUSSIAN OFFER TO MEDIATE

In a 20-year strategic partnership pact signed in January by President Vladimir Putin and Iranian President Masoud Pezeshkian, Russia did not undertake to help Tehran militarily and is under no obligation to do so despite the countries’ close military ties.

Putin, who has already lost an important partner in the Middle East with the fall of Syria’s Bashar al-Assad last December, spoke to US President Donald Trump by phone on Saturday. He offered Moscow’s services as a mediator, which Trump said he was open to before demanding Iran‘s “unconditional surrender.”

A source familiar with US internal discussions said Trump and his team were considering options including joining Israel in strikes against Iranian nuclear sites.

Sergei Markov, a former Kremlin adviser, has said the conflict – though opposed by Russia – could yield some benefits to Moscow including higher oil prices, more appetite from China for Russian oil because of difficulties sourcing Iranian oil and a reallocation of US military resources away from Ukraine.
