The US attacked three Iranian nuclear facilities on June 22, pushing itself into Israel's nine-day conflict with Iran in what President Donald Trump described as a mission that "completely and fully obliterated" key nuclear sites.

Iranian sources have disputed the damage, along with former US nuclear inspector Scott Ritter, who said the damage was not as impactful as the US claimed. The announcement of the strike also comes as satellite images via Maxar suggest that Iran emptied the site days earlier ahead of a strike on the Fordo facility.

US forces struck Iran's Fordo, Isfahan and Natanz nuclear facilities using B-2 stealth bombers carrying 30,000-pound bunker-buster bombs and approximately 30 Tomahawk missiles launched from submarines, according to US officials speaking on condition of anonymity.

Trump announced the strikes from the White House, stating: "We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan. All planes are now outside of Iran air space."

The Atomic Energy Organisation of Iran confirmed attacks occurred at the three sites but insisted its nuclear programme would continue. Iran and the UN nuclear watchdog reported no immediate signs of radioactive contamination following the strikes.

Iran's Foreign Ministry accused Washington of betraying diplomacy and launching "a dangerous war against Iran," whilst reserving "its right to resist with full force against US military aggression."

Hours after the American attacks, Iran's Revolutionary Guard launched 40 missiles at Israel, including Khorramshahr-4 missiles capable of carrying multiple warheads. Israeli authorities reported more than 80 people suffered mostly minor injuries, with damage reported in Haifa, Tel Aviv and coastal areas.

Israeli Prime Minister Benjamin Netanyahu praised Trump's decision, stating: "Your bold decision to target Iran's nuclear facilities, with the awesome and righteous might of the United States, will change history."

Trump acted without congressional authorisation and warned of additional strikes if Tehran retaliated against US forces. "There will either be peace or there will be tragedy for Iran," he said.

The International Atomic Energy Agency confirmed "no increase in off-site radiation levels" after the strikes but said it would continue monitoring the situation.

UN Secretary-General António Guterres called the strikes a "dangerous escalation," warning of growing risks the conflict "could rapidly get out of control."

Russian Foreign Minister Sergey Lavrov warned that "complete chaos" would ensue if the right to self-defence is applied without regard to the UN Charter, commenting on Israeli strikes against Iran, Tass reported.

"If the right to self-defence is applied without taking into account the UN Charter, complete chaos will ensue," Lavrov said regarding the Israeli attacks on Iran, according to the Russian Foreign Ministry press service.

Earlier, The International Atomic Energy Agency will convene an emergency meeting on June 23 to discuss American strikes on Iranian nuclear facilities, IAEA Director General Rafael Grossi announced.

"In connection with the emergency situation in Iran, I am calling an emergency meeting of the IAEA Board of Governors tomorrow," Grossi wrote on his X account on June 22.

The IAEA Board of Governors comprises 35 member states responsible for overseeing the agency's activities and nuclear safeguards implementation.

Iran has said that Grossi is directly responsible for the current war with Israel after it said he was complicit with plans for an attack, according to senior Iranian official Ali Larijani.
