Iran on Wednesday formally suspended its cooperation with the UN nuclear watchdog, a measure drawn up in the wake of unprecedented Israeli and US strikes on the Islamic republic's nuclear sites.
The war between Iran and Israel, which broke out on June 13 and lasted for 12 days, has intensified tensions between Tehran and the International Atomic Energy Agency (IAEA).
On June 25, a day after a ceasefire took hold, Iranian lawmakers overwhelmingly voted in favour of the bill to suspend cooperation with the agency. State media said on Wednesday that the legislation had cleared the final hurdle and was in effect.
The text, published by Iranian media, states that the legislation aims to "ensure full support for the inherent rights of the Islamic Republic of Iran" under the nuclear non-proliferation treaty, and "especially uranium enrichment."
The issue of enrichment was at the core of disagreements between Washington and Tehran in nuclear negotiations that had been derailed by the war.
Israel and some Western countries had for long accused Iran of seeking to quire nuclear weapons — an ambition Tehran has consistently denied.
The text of the law did not specify concrete moves linked to the suspension of cooperation with the IAEA, whose inspectors have had access to declared nuclear facilities. Following the parliament vote, the bill was approved by the Guardian Council, a body tasked with vetting legislation, before a final ratification from the presidency.
Iranian President "Masoud Pezeshkian promulgated the law suspending cooperation with the International Atomic Energy Agency," state TV said on Wednesday.
Iranian officials have sharply criticised the IAEA for what they described as the agency's "silence" in the face of the Israeli and US attacks on Iranian nuclear sites.
'Deceptive and fraudulent'
Tehran has also lambasted the UN agency for a resolution adopted on June 12 that accuses Iran of non-compliance with its nuclear obligations. Iranian officials said the resolution was among the "excuses" for the Israeli attacks.
On Wednesday, senior judiciary official Ali Mozaffari said that IAEA director Rafael Grossi should "be held accountable" for what he called "preparing the groundwork for the crime" against Iran, referring to Israel's air raids.
Mozaffari accused Grossi of "deceptive actions and fraudulent reporting", according to Iranian news agency Tasnim. Iran has rejected a request from Grossi to visit nuclear facilities bombed during the war, and earlier this week Pezeshkian decried his "destructive" conduct.
Iran has said Grossi's request to visit the bombarded sites signalled "malign intent" but insisted there were no threats against him or against inspectors from his agency. France, Germany and Britain have condemned unspecified "threats" against the IAEA chief.
