Iran live updates: IAEA inspectors will visit Iranian nuclear sites, but timing is unclear, director general says

The U.N.’s nuclear watchdog will inspect nuclear sites in Iran under the terms of the memorandum of understanding signed by Iran and the United States, the group's director general said on Wednesday.

When those inspections will happen is a different matter, Rafael Grossi, director general of the International Atomic Energy Agency, told reporters in Japan on Wednesday.

"Whether this happens the day after tomorrow or in one week or in ten days, it's important, but not essential," Grossi said. "This is going to happen. Of course, if they want to comply with the agreement. If they don't want, it's another matter."

He pointed to one of the terms in the memorandum, saying it "says explicitly that the nuclear activities that are going to be carried out with the regards of the nuclear material facilities will be supervised by the IAEA."

President Donald Trump on Tuesday said Tehran had agreed to those inspections. A spokesperson for Iran’s Foreign Ministry earlier in the day said the country didn’t "have any plans" to allow IAEA teams to visit sites damaged during the current war and the 12-day war in 2025.

The Senate has adopted a House-approved Iran War Powers resolution 50-48 in a symbolic, yet rare, rebuke of President Donald Trump.

Republican Sens. Bill Cassidy, Susan Collins, Maine, Lisa Murkowski, Alaska, and Rand Paul, Kentucky, voted in favor of the resolution while Democrat Sen. John Fetterman, Pennsylvania, voted against it. The four Republican Senators that voted for the resolution have previously joined Democrats on other Iran War Power votes.

Because this is a concurrent resolution, it does not require the president’s signature nor does it carry the force of law; however, it is emblematic of the growing concern both chambers have now voiced with Trump’s handling of the war.

Tuesday's rebuke comes as Trump is expected to huddle with Republican senators on Wednesday to speak on a wide range of topics. Multiple Senators said they are hoping to garner more information out of Trump on the ongoing negotiations with Iran.

President Donald Trump maintained his claims that Iran has agreed to nuclear inspections, telling reporters on Tuesday that he’d "cancel the meetings right now" if they didn’t comply.

Trump said that Iran would allow inspectors into their country but claimed there was currently "no rush" to send them.

Despite the fact that an Iranian Foreign Ministry spokesperson said there is no scheduled meeting with International Atomic Energy Agency inspectors, Trump remained firm in his argument that it will take place and said the Iranians are “wrong” in their public statements.

Pressed on when the inspectors will actually be on the ground in Iran, Trump said "at the appropriate time."
