Rafael Grossi, director general of the International Atomic Energy Agency (IAEA), said there were no signs that any nuclear facilities in Iran had been attacked by the United States and Israel.
On the 2nd (local time), Grossi said in a keynote address to the board of governors in Vienna, Austria, "So far, there are no indications that nuclear facilities in Iran or in other countries in the region have been attacked," adding, "No increases in radiation levels exceeding normal values have been detected in Iran's neighboring countries."
Mohammad Eslami, Iran's vice president and head of the Atomic Energy Organization of Iran (AEOI), claimed in a letter to Grossi that there had been two U.S. and Israeli airstrikes the previous day on nuclear facilities in Natanz and argued a violation of international law, but Grossi flatly refuted this.
However, Grossi warned that there is a risk of a nuclear-related accident occurring amid the escalation in the Middle East.
He noted that several Gulf countries with nuclear facilities had recently come under attack, urging restraint in military operations, saying, "There is also a possibility of a serious radiological release incident that would require evacuations on a scale larger than major cities."
Grossi also said there is no evidence that Iran has systematically pursued a nuclear weapons development program, but he did not rule out the possibility that the United States might have obtained related information unknown to the IAEA.
Earlier, President Donald Trump, launching an attack on Iran on the 28th of last month, said, "Iran tried to rebuild its nuclear program," adding, "Iran must never have nuclear weapons."
Grossi explained, "IAEA researchers have been unable to access Iran's key nuclear facilities for more than eight months," and "We have been unable to verify whether nuclear material has been diverted for military purposes."
