The big question following U.S. and Israeli attacks on Iran’s nuclear program is: What remains of it.

A new U.S. intelligence report suggests that Iran’s nuclear program has been set back only a few months after U.S. strikes, not “completely and totally obliterated” as President Donald Trump has said.

The United States has joined Israel in its attacks on Iran’s nuclear program.

U.S. President Donald Trump has posted an ominous message on his social media site, calling for the immediate evacuation of Tehran but later denied reports that he'd rushed back to Washington to work on a ceasefire.

The head of the International Atomic Energy Agency says there is a possibility of both radiological and chemical contamination within Iran’s main nuclear enrichment facility in Natanz.

U.S. forces have attacked three Iranian nuclear and military sites, further upping the stakes in the Israel-Iran war.

Israel supplied Iran with centrifuge platforms containing explosives for its nuclear enrichment program in an act of sabotage.

Iran will begin enriching uranium with thousands of advanced centrifuges at its two main nuclear facilities at Fordo and Natanz.

The head of Iran’s nuclear program is insisting that his nation will cooperate with international inspectors on any “new activities” regarding its nuclear sector.

A senior Iranian official has offered a cautiously upbeat assessment of progress in talks aimed at bringing the United States back into world powers’ 2015 deal with Tehran on its nuclear program.

Iran says it has begun enriching uranium to its highest-ever purity, edging close to weapons-grade levels.

Iran’s supreme leader says the offers being made at the Vienna talks over his country’s tattered nuclear deal “are not worth looking at.”.

An Iranian nuclear negotiator says Tehran will begin enriching uranium up to 60% purity after an attack on its Natanz nuclear facility.

Indirect talks between Iran and the United States on reviving the 2015 nuclear deal have been thrown into uncertainty following an attack on Iran's underground Natanz nuclear facility.

Indirect talks between Iran and the United States on reviving the 2015 nuclear deal have been thrown into uncertainty following an attack on Iran's underground Natanz nuclear facility.

Iran has blamed Israel for an attack on its underground Natanz nuclear facility that damaged its centrifuges.

Iran’s nuclear program has been targeted by diplomatic efforts and sabotage attacks over the last decade, with the latest incident striking its underground Natanz facility.

DUBAI – Iran has begun construction at its Natanz nuclear facility, satellite images released Wednesday show, just as the U.N. nuclear agency acknowledged Tehran is building an underground advanced centrifuge assembly plant after its last one exploded in a reported sabotage attack last summer. “Nothing in Iran regarding its peaceful nuclear program is being done in secret, in full keeping with the JCPOA, and as the IAEA has repeatedly confirmed,” Miryousefi said in an email. Iran maintains its nuclear program is for peaceful purposes, though Western countries fear Tehran could use it to pursue atomic weapons. Despite being one of the most-secure sites in Iran, Natanz was targeted by the Stuxnet computer virus — believed to be the creation of the U.S. and Israel — before the nuclear deal. There have been tensions with the IAEA and Iran even at Natanz, with Tehran accusing one inspector of testing positive for explosives last year.

Following the July explosion at the Natanz nuclear site, Tehran said it would build a new, more secure, structure in the mountains around the area. Ali Akbar Salehi, the head of Iran's nuclear department, last month told state television the destroyed above-ground facility was being replaced with one “in the heart of the mountains around Natanz.”Natanz hosts the country’s main uranium enrichment facility. Natanz became a flashpoint for Western fears about Iran’s nuclear program in 2002, when satellite photos showed Iran building an underground facility at the site, some 200 kilometers (125 miles) south of the capital, Tehran. In 2003, the IAEA visited Natanz, which Iran said would house centrifuges for its nuclear program, buried under some 7.6 meters (25 feet) of concrete. Still though, Iran has continued to allow IAEA inspectors full access to its nuclear facilities, including Natanz, Grossi said.

TEHRAN Iran on Sunday confirmed that a damaged building at the underground Natanz nuclear site was a new centrifuge assembly center, the official IRNA news agency reported. A spokesman for Irans nuclear agency, Behrouz Kamalvandi, said Sunday that work had begun on the center in 2013 and it was inaugurated in 2018. Iran began experimenting with advanced centrifuge models in the wake of the U.S. unilaterally withdrawing from the deal two years ago. Two U.S.-based analysts who spoke to The Associated Press on Friday, relying on released pictures and satellite images, identified the affected building as Natanzs new Iran Centrifuge Assembly Center. Currently, the IAEA says Iran enriches uranium to about 4.5% purity above the terms of the nuclear deal but far below weapons-grade levels of 90%.

An online video and messages purportedly claiming responsibility for a fire that analysts say damaged a centrifuge assembly plant at Iran's underground Natanz nuclear site deepened the mystery Friday around the incident even as Tehran insisted it knew the cause but would not make it public due to "security reasons."

Iranian nuclear officials did not respond to a request for comment from the AP on the analysts' findings. A video claimed the group included soldiers from the heart of regimes security organizations who wanted to stop Iran from acquiring a nuclear weapon.

The Atomic Energy Organization of Iran sought to downplay the fire Thursday, calling it an incident that only affected an industrial shed. (Atomic Energy Organization of Iran via AP)TEHRAN A fire broke out early Thursday at a building above Iran's underground Natanz nuclear enrichment facility, though officials said it did not affect its centrifuge operation or cause any release of radiation. A photograph later released by the atomic energy agency showed a brick building with scorch marks and its roof apparently destroyed.
