Iran will react to any reimposition of United Nations sanctions over its nuclear program, the country’s foreign ministry spokesperson says, without elaborating on what actions Tehran might take.

A French diplomatic source told Reuters last week that European powers would have to restore UN sanctions on Iran under the so-called “snapback mechanism” if there were no nuclear deal that guaranteed European security interests.

The “snapback mechanism” is a process that would reimpose UN sanctions on Tehran under a 2015 nuclear deal that lifted the measures in return for restrictions on Iran’s nuclear program.

“The threat to use the snapback mechanism lacks legal and political basis and will be met with an appropriate and proportionate response from the Islamic Republic of Iran,” Foreign Ministry spokesperson Esmaeil Baghaei tells a press conference, without giving further details.

The 2015 deal with Britain, Germany, France, the US, Russia and China – known as the Joint Comprehensive Plan of Action (JCPOA) – states that if the parties cannot resolve accusations of “significant non-performance” by Iran, the “snapback mechanism” process can be triggered by the 15-member UN Security Council.

“The European parties, who are constantly trying to use this possibility as a tool, have themselves committed gross and fundamental violations of their obligations under the JCPOA,” Baghaei says.

“They have failed to fulfill the duties they had undertaken under the JCPOA, so they have no legal or moral standing to resort to this mechanism.”

Western countries accuse Iran of plotting to build a nuclear weapon, which Tehran denies.
