Isfahan, Natanz and Fordow: What we know about the US strikes on Iran's nuclear facilities

Details are emerging about the US strikes against Iran's nuclear facilities.

Reports are coming in about which sites have been hit and what military elements have been used, as President Donald Trump hails the attack on social media.

From the number of bunker buster bombs dropped to where they hit, here's what we know so far.

Which sites were hit?

America appears to have hit the three key locations in Iran's nuclear programme.

They include Isfahan, the location of a significant research base, as well as uranium enrichment facilities at Natanz and Fordow.

Natanz was believed to have been previously damaged in Israeli strikes after bombs disrupted power to the centrifuge hall, possibly destroying the machines indirectly.

Details about the damage in the US strikes are not yet known, although Mr Trump said the three sites had been "obliterated".

What weapons were used in the attacks?

The White House and Pentagon did not immediately elaborate on the operation, but a US official said B-2 heavy bombers were involved.

Fox News host Sean Hannity said he had spoken with the president and that six bunker buster bombs were used on the Fordow facility.

Bunker buster bombs are designed to explode twice. Once to breach the ground surface, and again, once the bomb has burrowed down to a certain depth.

Israel has some in its arsenal but does not have the much more powerful GBU-57, which can only be launched from the B-2 bomber and was believed to be the only bomb capable of breaching Fordow.

However, most of the highly enriched uranium at the Fordow nuclear facility was moved to an undisclosed location ahead of the attack, a senior Iranian source told the Reuters news agency.

Personnel numbers were also reduced at the site, according to the report.

Satellite images from Fordow show cargo trucks lining up at the entrance of the nuclear site in recent days.

The New York Times reported a US official as saying a B-2 also dropped two bunker buster bombs on Natanz.

Hannity said 30 Tomahawk missiles fired by US submarines 400 miles away struck the Iranian nuclear sites of Natanz and Isfahan.

How has Iran responded so far?

Iran's foreign minister Abbas Araghchi warned that the US strikes "will have everlasting consequences", adding that his country "reserves all options" to retaliate.

"The events this morning are outrageous and will have everlasting consequences," Mr Araghchi wrote on X. "Each and every member of the UN must be alarmed over this extremely dangerous, lawless and criminal behaviour."

Iran has requested an emergency meeting of the UN Security Council to "maintain international peace and condemn the US strikes", according to state media.

Multiple places in Israel have been hit by Iranian missiles in response.

Several explosions have been heard over Tel Aviv with Israeli media saying missiles have hit northern and central Israel, including in Haifa, Ness Ziona, Rishon LeZion and Tel Aviv.

16 casualties were reported by the country's emergency services.

Abbas Golroo, head of the Iranian parliament's foreign policy committee, also said Iran could pull out of efforts to limit the spread of nuclear technology and weapons in a statement on social media.

He cited Article 10 of the treaty, which states that an NPT member has "the right to withdraw from the treaty if it decides that extraordinary events have jeopardised the supreme interests of its country".
