There is “no indication” that Iranian nuclear sites have been damaged in the current U.S.-Israeli war against the Islamic regime, International Atomic Energy Agency head Rafael Grossi said on Monday.

Grossi told the body’s Board of Governors during an emergency meeting in Vienna that while efforts to contact Iranian nuclear authorities continue, his organization has received “no response so far.”

He went on to say that “so far, no elevation of radiation levels above the usual background levels has been detected in countries bordering Iran.”
