Rubio condemns Iran's 'unacceptable' threats against IAEA director

"We support the lAEA's critical verification and monitoring efforts in Iran and commend the Director General and the lAEA for their dedication and professionalism," Rubio wrote in an X post. "We call on Iran to provide for the safety and security of IAEA personnel."

The lAEA this week commented on damage at Iranian nuclear facilities, following U.S. airstrikes on key nuclear sites in Iran, including Fordow, Natanz and Isfahan.

"I have to be very precise, Martha," Grossi said. "We are the IAEA, so we are not speculating here. We do not have information of the whereabouts of this material."

"My job is to try to see where is this material, because Iran has an obligation to report and account for all the material that they have, and this is going to continue to be my work," Grossi said.

Rubio did not immediately respond to Fox News Digital's request for comment.
