A new resolution has been passed at the UN nuclear watchdog, voicing “increasing concern” about Iran’s nuclear programme.
The US has seized on the resolution as proof that Iran is not being truthful when it says its nuclear ambitions are only for civilian purposes.
Some reports say Washington is now planning sanctions on Iran’s petrochemical industry.
The head of the Iranian delegation to the IAEA, Ali Asghar Soltanieh, told euronews that as a gesture of goodwill they had earlier sent a letter inviting IAEA officials to Tehran.
But it is now certain the latest resolution puts that invitation in doubt.
The International Atomic Energy Agency did not mention any punitive measures in its latest vote.
Our correspondent in Vienna, Nima Ghadakpour, says although the resolution was another move against Iran’s nuclear programme, it was not strong enough to worry the Iranian authorities.
Earlier this week Iranians formed a human chain around an atomic facility in a show of support for the country’s nuclear programme.
Iran denies fresh reports that it is trying to make an atomic bomb, claiming allegations in the West are based on fabricated US, Israeli, UK and French intelligence.
