VIENNA, June 18 (Xinhua) -- Two centrifuge production facilities in Iran, the TESA Karaj workshop and the Tehran Research Center, have been struck, the International Atomic Energy Agency (IAEA) said on Wednesday.

Both sites were previously under the monitoring and verification regime of the IAEA as part of the Joint Comprehensive Plan of Action, the agency said in a post on social media platform X.

At the Tehran site, one building was hit while at the other site, two buildings were destroyed.

On Friday, the IAEA called for an end to attacks on nuclear facilities. "Nuclear facilities must never be attacked, regardless of the context or circumstances," IAEA Director General Rafael Grossi said at the Board of Governors meeting.

"Such attacks have serious implications for nuclear safety, security and safeguards, as well as regional and international peace and security," he said. ■
