VIENNA, March 27 (Xinhua) -- The International Atomic Energy Agency (IAEA) chief has once again urged military restraint following an attack on Iran's yellowcake production facility on Friday.

The IAEA said on social media platform X that it had been informed by Iran that a yellowcake production plant in central Iran's Yazd province was attacked on Friday.

There was no report of an increase in off-site radiation levels, the IAEA said, adding that it was looking into the matter.

IAEA Director General Rafael Grossi reiterated his call for military restraint to avoid any risk of a nuclear accident.

The plant, inaugurated in May 2023, produces yellowcake, a uranium concentrate powder obtained from leach solutions and serving as an intermediate step in the processing of uranium ores. ■
