This weekend, President Trump declared that Iran’s nuclear capabilities were “completely and totally obliterated” by U.S. airstrikes. The full extent of the damage, which is being assessed by U.S. spy agencies, is still unclear.

Several disclosures and claims by U.S. and United Nations officials, along with satellite images taken after the U.S. and Israeli airstrikes, have shed some light on the situation in Iran:

• A leaked U.S. intelligence report said the attacks set back Iran’s nuclear program by only a few months — a finding disputed by Mr. Trump.

• The C.I.A. director, John Ratcliffe, said on Wednesday the strikes had “severely damaged” Iran’s nuclear program.

• Rafael Grossi, the head of the International Atomic Energy Agency, said on Thursday that centrifuges at the deeply buried Fordo uranium enrichment plant are “no longer operational,” but that it would be “too much” to assert that Iran’s nuclear program had been “wiped out.”

Here’s what we know so far about the state of Iran’s nuclear program after the Israeli and U.S. attacks:

Fordo

Iran built the Fordo Fuel Enrichment Plant deep inside a mountain, impervious to all but a repeated assault from American “bunker buster” bombs. A U.S. official said that six B-2 bombers dropped a dozen 30,000-pound bombs on Fordo on Sunday.

The Fordo site contained thousands of Iran’s most advanced centrifuges to enrich uranium, which could be used in a nuclear weapon. In 2023, the International Atomic Energy Agency, the U.N. nuclear watchdog, reported that it had discovered uranium that had been enriched to 83.7 percent purity at Fordo — just under the 90 percent required for a weapon.

Satellite images taken shortly after the U.S. airstrikes reveal damage and likely entry points for the American bunker-buster bombs. The images show distinct changes in the ground’s appearance and gray dust near the possible strike locations.
