ERBIL, Kurdistan Region of Iraq – Iran on Wednesday warned the International Atomic Energy Agency (IAEA) that tolerating threats made by Washington would damage the agency’s credibility and shake international trust in its work.

US President Donald Trump on Monday warned that Washington would “absolutely” and “immediately” support potential renewed Israeli military actions targeting Iran if Tehran continues developing its nuclear and missile programs.

Iran’s Permanent Representation to the United Nations Office in Vienna said in a post on X that it has forwarded a letter to IAEA chief Rafael Grossi, warning of “severe consequences for the global non-proliferation regime,” in light of the UN watchdog’s silence toward Trump’s remarks.

“Normalizing such threats endangers the IAEA’s credibility and undermines the international confidence built upon its verification word,” said the mission, calling on Grossi to condemn “such reckless acts.”

Iran and the US held five rounds of indirect nuclear talks before Israel launched an attack on Iranian military commanders and nuclear scientists, which Washington joined by bombing key nuclear facilities.

Following the 12-Day War and the reimposition of crippling sanctions on Iran for not fulfilling its nuclear obligations, dialogue between Tehran and Western states has grinded to a frosty halt.

Since the end of the war, Tehran has routinely blocked the IAEA from maintaining oversight of its facilities, citing the termination of the nuclear deal’s commitments.

In September, the UN reimposed crippling sanctions on Tehran for allegedly failing to fulfill its nuclear commitments. In turn, Iran blocked the nuclear watchdog from maintaining oversight of its facilities, citing the termination of the nuclear deal’s commitments.

While the US demands the full termination of Iran’s nuclear program, Tehran claims its uranium enrichment is used for “peaceful purposes” and refuses to halt its activity.
