Rafael Grossi, director general of the International Atomic Energy Agency (IAEA), said in a Sunday interview that recent U.S.-Israeli military operations against Iran have had a "relatively marginal" impact on the country's nuclear program.

Grossi noted that the current campaign has not inflicted as much damage to Iran's nuclear facilities as strikes conducted by U.S. and Israeli forces last June. The IAEA chief indicated that this round of military action appears to have focused on different targets than Iran's nuclear infrastructure.

The assessment comes as the conflict involving Iran has entered its fourth week, according to reports. International observers have been monitoring potential impacts on both Iran's nuclear capabilities and broader regional stability.

The IAEA, as the United Nations' nuclear watchdog agency, regularly monitors nuclear facilities and programs in member countries. Grossi's comments provide an official assessment of how recent military operations may have affected Iran's nuclear development efforts.

The June strikes referenced by Grossi had apparently caused more significant damage to Iran's nuclear program infrastructure, though specific details of those operations and their impacts were not elaborated upon in the available reports.
