Iran’s Foreign Minister Abbas Araghchi will have a joint phone call with his French, British and German counterparts on Friday to discuss nuclear talks and sanctions.

Axar.az reports, citing Reuters, the three European powers have threatened to activate United Nations sanctions on Iran under a “snapback” mechanism if Iran does not return to the negotiating table over its nuclear program.

The countries, along with the United States, contend Iran is using the nuclear program to potentially develop weapons, which Iran denies.

Tehran suspended negotiations with the US, which were aimed at curbing the Islamic Republic’s nuclear ambitions, after the US and Israel struck its nuclear sites in June.

Since then, inspectors from the International Atomic Energy Agency have been unable to access Iran’s nuclear installations, despite IAEA chief Rafael Grossi stating that inspections remain essential.
