Iran-Israel conflict updates: World urges de-escalation after US strikes on Iranian nuclear sites

The International Atomic Energy Agency (IAEA) has confirmed that entrances to underground tunnels at Iran’s Isfahan nuclear complex were damaged in the recent US military strikes.

“We have established that entrances to underground tunnels at the site were impacted,” the UN nuclear watchdog said in a statement.

Prior to the June 13 Israeli strike on Iranian nuclear facilities, officials had noted that a significant portion of Iran’s highly enriched uranium was stored underground at the Isfahan site.

United Nations chief Antonio Guterres warned Sunday against yet "another cycle of destruction" and retaliation following the US strikes against Iran, which he said marked a "perilous turn" in the region.

"I have repeatedly condemned any military escalation in the Middle East," the secretary-general told an emergency meeting of the UN Security Council. "The people of the region cannot endure another cycle of destruction. And yet, we now risk descending into a rathole of retaliation after retaliation."

Israel has "moved closer" to its goals in Iran after US President Donald Trump ordered overnight bombing raids on the Islamic republic's nuclear sites, Israeli Prime Minister Benjamin Netanyahu said Sunday.

"We have achieved a great deal, and thanks to President Trump, we have moved closer to our goals," Netanyahu said in a televised press conference, adding that "when they have been reached, the operation will finish".

The Israeli military has announced it is currently targeting "military infrastructure" in Tehran and western Iran.

Meanwhile, Iranian media have reported explosions in the western city of Kermanshah.

The B-2 Spirit stealth bombers that dropped massive bunker-buster bombs on Iranian nuclear sites have started returning to Whiteman Air Force Base in Missouri.

An Associated Press reporter observed at least seven of the bombers landing on a clear but windy Sunday afternoon. Four aircraft first circled the base before landing from the north, followed by three more arriving within 10 minutes.

US officials revealed that one group of B-2s departed westward from Missouri on Saturday as a decoy to confuse Iranian forces, while another group of seven flew east and carried out the mission in Iran.

Yemen’s Houthi rebels have denounced the US attack on Iran’s nuclear sites, calling it a “cowardly” act and a clear violation of international law.

In a statement, the group warned that the strike threatens regional and global peace and security. They described the attack as part of the US’s “unlimited criminal support” for Israel, targeting Iran for its strong backing of the Palestinian cause and resistance movements.

The Houthis affirmed that this aggression will not stop Iran from continuing its “path of resistance” against the US and Israel.

An advisor to Iran's supreme leader said Sunday that the United States "no longer" has a place in the Middle East after it conducted strikes against nuclear facilities in the Islamic republic.

"There is no longer any place for America or its bases in this region and the Islamic world," said Ali Akbar Velayati in a message carried by the official IRNA news agency.

"America has attacked the heart of the Islamic world and must await irreparable consequences, because the Islamic Republic does not tolerate any insult or aggression against itself," he added.

Foreign ministers from countries of the Organisation of Islamic Cooperation (OIC) on Sunday urged Israel to end its "aggression" towards Iran, without mentioning the US strikes on the Islamic republic's nuclear sites.

The ministers "condemn firmly the aggression of Israel against the Islamic Republic of Iran, stress the urgent need to stop Israeli attacks and their great concern regarding this dangerous escalation", said an OIC statement

It was published at the end of a OIC meeting in Istanbul this weekend.

It made no direct reference to the US bombardment of Iran's key nuclear facilities early Sunday, after President Donald Trump decided to join Israel's strikes on Iran's nuclear programme.

But the OIC did denounce the "destabilization policies of Israel in the region and its recent attacks on Iran, Syria, and Lebanon, constituting flagrant (a) violation of sovereignty and security of these countries and international law".

Attending the OIC meeting, Iran's top diplomat Abbas Araghchi said Sunday morning that the United States and Israel had "breached a major red line".

Tehran would hit back at the American barrage "by all means necessary", he added.

Over 200 places in the Iranian capital have been hit in Israeli strikes since the start of the conflict ten days ago, Tehran's provincial governor said on Sunday.

"More than 200 locations have been attacked by the usurping Zionist regime," governor Mohammad Sadegh Motamedian told state TV.

He said over 120 residential housing units "have been fully destroyed" while 500 others suffered "damages."

An adviser to Iran's supreme leader Ayatollah Ali Khamenei said Sunday that the country still had its stockpile of enriched uranium despite attacks by the United States on key nuclear sites.

"Even if nuclear sites are destroyed, game isn't over, enriched materials, indigenous knowledge, political will remain," said Ali Shamkhani in a post on X.

He added that the "political and operational initiative is now with the side that plays smart, avoids blind strikes. Surprises will continue!"

The UK, France, and Germany have jointly urged Iran to refrain from taking any further actions that could destabilise the Middle East, according to a report by the BBC.

In a joint statement, British Prime Minister Keir Starmer, French President Emmanuel Macron, and German Chancellor Friedrich Merz reiterated their long-standing position that Iran must never acquire a nuclear weapon. They also expressed strong support for Israel’s security.

Addressing the recent US strikes on Iran, the leaders said, “Our aim continues to be to prevent Iran from acquiring a nuclear weapon.”

They called on Iran to return to the negotiating table to secure a comprehensive agreement addressing all concerns related to its nuclear programme.

“We stand ready to contribute to that goal in coordination with all parties,” the statement added.

At least nine members of the Revolutionary Guards were killed Sunday in Israeli attacks on central Iran, local media reported, as fighting between the two foes continued.

"Following the aggression of the barbaric Zionist regime and its mercenaries against two military centres in Yazd city, seven Islamic Revolutionary Guards Corps personnel and two conscripts were martyred," the Tasnim news agency reported, quoting an IRGC statement.

Others were injured in the attack, it added. The Fars news agency had earlier said Israeli strikes targeted two military sites in Yazd.

The United States has ordered non-essential staff and families of diplomats to leave Lebanon, citing heightened security concerns following its airstrikes on Iranian nuclear facilities.

In a statement on June 22, the US Embassy in Beirut said the move was prompted by “the volatile and unpredictable security situation in the region.”

“The US Department of State ordered the departure of family members and non-emergency US government personnel from Lebanon,” the embassy announced.

Lebanon remains under the State Department’s highest travel advisory — “Do Not Travel” — with US citizens strongly urged to avoid the country entirely.

Major US cities including New York, Washington, DC, and Los Angeles are ramping up security following US airstrikes on Iranian nuclear sites, which have intensified tensions in the Middle East and raised concerns over potential retaliation.

• No credible threats reported, but officials stress the need for vigilance.

• New York has deployed extra officers citywide, focusing on religious, cultural, and diplomatic sites.

• NYPD is coordinating with federal agencies and has embedded personnel abroad, including in Israel, for real-time updates.

• Washington, DC police are closely monitoring developments and working with federal partners.

• Los Angeles has increased patrols at sensitive sites; the mayor says the city is on high alert as a precaution.

• Advanced intelligence tools, surveillance systems, and multilingual support are being used to detect and respond to threats swiftly.

The United States would allow Iran to operate nuclear power plants but not enrich its own fuel, Secretary of State Marco Rubio said, after a wave of American strikes aimed to wipe out Iran's nuclear program.

"The Iranian regime should wake up and say 'OK, if we really want nuclear energy in our country, there's a way to do it.' That offer's still there, we're prepared to talk to them tomorrow," he told Fox News.

"Ultimately, they have to make a decision. It's a very simple decision: if what they want is nuclear reactors so they can have electricity - there are so many other countries in the world that do that, and they don't have to enrich their own uranium - they can do that," Rubio added.

Iran said on Sunday that it was ready to defend itself by "all necessary means" after unprecedented US strikes on its nuclear facilities.

"Iran is resolutely determined to defend its national sovereignty, territorial integrity, national security and people by all necessary means," foreign ministry spokesman Esmaeil Baqaei posted on X, condemning what he described as an "unconscionable act of aggression - perpetrated by a nuclear-armed state... against a non-nuclear weapon country".

Iran's President Masoud Pezeshkian took part in a protest in Tehran on Sunday denouncing US strikes on Iranian nuclear facilities, according to images broadcast on state TV.

"Revenge, revenge!" protesters shouted with their fists raised, as the president was seen making his way through the crowd gathered in a square in central Tehran

The Israeli military said its fighter jets had struck "dozens" of targets across Iran on Sunday, including a long-range missile site in Yazd in the centre of the country for the first time.

A statement said that "approximately 30 IAF (air force) fighter jets struck dozens of military targets throughout Iran", including "the 'Imam Hussein' Strategic Missile Command Center in the Yazd area, where long-range Khorramshahr missiles were stored".

Iran's atomic energy agency described US strikes on three key nuclear facilities as a "savage assault."

The "lawless actions" won't cause "the development of this national industry to be halted," the Atomic Energy Organization of Iran said in a statement, according to the state-run IRNA news agency.

The agency did not confirm whether the sites of Fordow, Natanz and Isfahan had been "completely and totally obliterated," as US President Donald Trump said they were in an address from Washington.

An Israeli army spokesperson confirmed that Israeli jets conducted dozens of airstrikes across Iran today, targeting military facilities in Isfahan, Bushehr, Ahvaz, and Yazd.

The strike in Yazd reportedly hit a site storing Khorramshahr ballistic missiles. In Isfahan, Bushehr, and Ahvaz, the attacks targeted missile launch platforms, air defense battery manufacturing sites, and a drone warehouse.

The army added that some strikes resulted in the deaths of Iranian military personnel detected operating at missile launch sites.

Vice President JD Vance said Sunday the US air strikes on Iran had significantly delayed its nuclear program - but added that Americans were not at war with the country itself.

"I don't want to get into sensitive intelligence here, but we know that we set the Iranian nuclear program back substantially last night, whether it's years or beyond," he told ABC.

"We're not at war with Iran - we're at war with Iran's nuclear program," he added. "And I think the president took decisive action to destroy that program last night."

Iran’s parliament has voted in favour of closing the strategic Strait of Hormuz, Iranian media reported on Sunday. The measure, however, still requires approval from the Supreme National Security Council to take effect.

The Strait of Hormuz is a critical maritime passage, with about 20% of the world’s oil and gas supply flowing through it.

While the closure is not yet confirmed, senior lawmaker and Revolutionary Guards commander Esmail Kosari told media that the move is “on the agenda and will be implemented whenever necessary.”

Iran's government said there was no immediate danger to the public after the United States struck three of its nuclear sites on Sunday.

"There is no danger to the people living on the outskirts of our nuclear areas," spokeswoman Fatemeh Mohajerani said on state television. "The people of Natanz, Isfahan and Fordo can continue their lives."

The US strikes that targeted Iran's nuclear sites involved submarines launching Tomahawk missiles and B-2 bombers dropping 14 bunker-buster bombs, the Pentagon said in the first public accounting of the operation.

The operation "- dubbed "Midnight Hammer" saw the US deploy B-2 stealth bombers from Whiteman Air Force Base in Missouri, Air Force General Dan Caine, the chairman of the Joint Chiefs of Staff, told reporters at a press conference Sunday morning. He said there are no reports of US forces coming under fire.

"This is a plan that took months and weeks of positioning and preparation, so that we could be ready when the President of the United States called," Defense Secretary Pete Hegseth said. "It took a great deal of precision. It involved misdirection and the highest of operational security."

The officials said 75 precision-guided weapons were used and the operation involved some 125 aircraft. Caine said the battle damage would take time to assess but "all three sites sustain extremely severe damage and destruction."

The flights to deliver the targets amounted to the second-longest flights in the B-2's operational history, according to Hegseth. The longest was a 40-hour round trip in October 2001 in the initial phase of the Afghanistan war.

The US defense chief said Sunday that strikes ordered by President Donald Trump overnight had "devastated" Iran's nuclear program and urged Iranian leaders to seek peace to avoid further attacks.

"We devastated the Iranian nuclear program," Defense Secretary Pete Hegseth told a Pentagon press briefing, adding that the operation "did not target Iranian troops or the Iranian people."

Trump "seeks peace, and Iran should take that path," Hegseth said.

US Defense Secretary Pete Hegseth emphasised that President Trump “seeks peace” despite recent tensions.

“President Trump said no nukes, he seeks peace, and Iran should take that path,” Hegseth stated.

He then cited Trump’s social media posts from the previous night, which warned that any retaliation from Iran would be met with force “far greater” than before.

“Iran would be wise to heed those words. He said it before, and he means it,” Hegseth added.

Secretary of Defense Pete Hegseth and Joint Chiefs Chairman Dan Caine will hold a news conference Sunday morning to provide updates on President Trump’s decision to strike three Iranian nuclear sites.

On Saturday evening, President Trump announced that the US had launched strikes on nuclear facilities at Fordo, Natanz, and Isfahan. In a national address later that night, he stated the sites “have been completely and totally obliterated.”

Iran’s Foreign Minister Abbas Araghchi warned that the US and Israel had crossed a major red line by attacking Iran’s nuclear facilities, calling the strikes a grave escalation.

Speaking at the OIC meeting in Istanbul, he vowed that Iran would defend itself “by all means necessary” against both US and Israeli aggression.

Araghchi dismissed calls for renewed negotiations, accusing the US of betraying diplomacy by backing what he called Israel’s illegal war.

He added that Iran had been pursuing diplomatic solutions but was instead met with force, proving, in his words, that Washington and Tel Aviv only respond to threats.

Iran's government said on Sunday that urban patrols of Basij paramilitaries and other forces had been increased to ensure security, on the 10th day of the Iran-Israel war.

"In line with the increased security that is needed, especially at night, the number of urban patrols has increased, and here we should express our gratitude to the Basij forces and all the popular forces (for that)," government spokeswoman Fatemeh Mohajerani said on state television.

The Israeli army said Sunday it had "other goals" in Iran and intended to continue its military offensive.

"We have other goals and we will continue to act until we attain them," army spokesman Effie Defrin told reporters in a televised press conference.

The Israeli military said Sunday it was checking the results of a US bombing raid on the deeply buried Iranian nuclear facility in Fordo, adding that it was "too soon" to know if enriched uranium stockpiles had been destroyed.

Asked whether Iran had removed enriched uranium from Fordo or if it had been buried under the rubble, army spokesman Effie Defrin told reporters: "We are constantly checking the situation. It is too soon to determine. I suppose we will know later on."

Israel is to temporarily reopen its airspace for flights from 1100 GMT on Sunday as it repatriates thousands of citizens left stranded overseas by its war with Iran, the country's airport authority said.

Israel's main Ben Gurion Airport near Tel Aviv "will open for landings from 02:00pm - 8:00pm as part of Operation Safe Return", the authority said in a statement, referring to the government's efforts to bring home citizens.

Iranian Foreign Minister Abbas Araghchi said on Sunday the United States and Israel "decided to blow up" diplomacy when they launched strikes on his country's nuclear sites.

In a post on X, Araghchi said Israel blew up negotiations between Tehran and Washington with its strikes on June 13, while the United States did the same to talks with European powers this week with its strikes on Sunday. Addressing European calls for Iran to return to negotiations, he asked "how can Iran return to something it never left".

Yemen's rebel government said on Sunday it supported a vow by its armed wing a day earlier to hit US ships in the Red Sea should Washington launch strikes on Iran.

"We affirm the Republic of Yemen's commitment to the armed forces' declaration that they were ready to target US ships and warships in the Red Sea," the government said in a statement after the United States launched attacks on Iran.

Bahrain, host of a major US naval base, on Sunday told most of its government employees to work from home until further notice after American air strikes on Iranian nuclear sites.

"A remote working system will be activated across ministries and government agencies, with a 70 percent work-from-home capacity," the official Bahrain News Agency said, citing "regional circumstances and current developments".

Qatar, host of the biggest US military base in the Middle East, on Sunday said it feared serious repercussions after US air strikes on nuclear facilities in Iran.

The foreign ministry "warns that the current dangerous escalation in the region may lead to catastrophic consequences at both the regional and international levels", a statement said.

"It calls on all parties to exercise wisdom, restraint, and to avoid further escalation."

The head of the UN's International Atomic Energy Agency (IAEA) has announced an "emergency meeting" at the organisation's headquarters in Vienna for Monday after the US struck three nuclear sites in Iran.

"In light of the urgent situation in Iran, I am convening an emergency meeting of the @IAEAorg Board of Governors for tomorrow," Rafael Grossi wrote on X on Sunday.

Oman, which was mediating nuclear talks between Washington and Tehran, on Sunday strongly condemned US strikes on nuclear sites in Iran.

The Gulf sultanate "expresses deep concern, denunciation and condemnation of the escalation resulting from the direct air strikes launched by the United States on sites in the Islamic Republic of Iran", the official Oman News Agency said.

Saudi Arabia expressed "great concern" after US air strikes on nuclear facilities in its giant neighbour Iran.

"The Kingdom of Saudi Arabia is following with great concern the developments in the sisterly Islamic Republic of Iran, represented by the targeting of Iranian nuclear facilities by the United States of America," the Saudi foreign ministry posted on X.

Iran's foreign ministry said the US attacks Sunday on nuclear facilities showed that Washington "will stop at no illegality or crime" to support Israel.

"It has now become abundantly clear to all that the very regime which enjoys permanent membership in the Security Council is beholden to no principle or morality and will stop at no illegality or crime to serve the aims of a genocidal, occupying regime," the ministry said in a statement, referring to the United States and Israel respectively.

Iraq warned on Sunday that the US attacks on its neighbour Iran's nuclear facilities threaten peace and stability in the Middle East.

Iraq "expresses its deep concern and strong condemnation of the targeting of nuclear facilities" in Iran, government spokesperson Basim Alawadi said. "This military escalation constitutes a grave threat to peace and security in the Middle East and poses serious risks to regional stability," he added.

The Israeli military said it launched a fresh series of strikes Sunday targeting military targets including missile launchers in western Iran after the United States attacked the country's nuclear sites.

The air force began "a series of strikes toward military targets in western Iran", a military statement said, adding it had "struck missile launchers ready to launch toward Israeli territory, soldiers in the Iranian Armed Forces, and swiftly neutralised the launchers that launched missiles toward Israeli territory a short while ago".

Iran's armed forces said Sunday they targeted multiple sites in Israel including Ben Gurion airport, after US attacks on key nuclear sites in the Islamic republic.

"The twentieth wave of Operation Honest Promise 3 began using a combination of long-range liquid and solid fuel missiles with devastating warhead power," the armed forces said in a statement quoted by Fars news agency. The targets included the airport, a "biological research centre", logistics bases and various layers of command and control centres, it added.

The UN's International Atomic Energy Agency (IAEA) on Sunday said that it had not detected any increase in radiation levels at key nuclear sites in Iran following US air strikes.

"Following attacks on three nuclear sites in Iran... the IAEA can confirm that no increase in off-site radiation levels has been reported as of this time," the nuclear watchdog posted on X, just hours after US President Donald Trump said the strikes had "totally obliterated" Iran's main nuclear sites at Fordo, Isfahan and Natanz.

At least 23 people were hurt and at least one impact was reported in central Israel after Iran launched two waves of missiles following the US bombing of its nuclear sites, rescue services and reports said.

Israel's Magen David Adom rescue service said in a statement that "11 people were taken to hospital, including one in moderate condition - a 30-year-old man wounded in the upper body by shrapnel."

Public broadcaster KAN 11 showed images of a devastated building surrounded by mounds of rubble that it said was in central Israel, following the two waves of missiles launched at Israel from around 7:30 am (0430 GMT).

Iran's state TV announced on Sunday new missile launches against Israel after Tel Aviv's closest ally the United States bombed several Iranian nuclear sites.

"These live images you are seeing are of a new salvo of Iranian missiles fired on the occupied territories," said a presenter on air, referring to Israel. Citing "sources", a presenter said that "30 missiles have been launched at Israel from Iran".

Israel's military said on Sunday that it was working to intercept missiles launched from Iran, as air raid sirens rang out in Tel Aviv and explosions rocked Jerusalem.

"A short while ago, sirens sounded in several areas across Israel following the identification of missiles launched from Iran toward the State of Israel," the military said in a statement.

"At this time, the (Israeli Air Force) is operating to intercept and strike where necessary to eliminate the threat."

Iran's Foreign Minister Abbas Araghchi on Sunday condemned US attacks on key nuclear sites as "outrageous" and said his country has a right to defend its sovereignty.

"The events this morning are outrageous and will have everlasting consequences," he posted on X, adding that the attacks were "lawless and criminal" behaviour.

"In accordance with the UN Charter and its provisions allowing a legitimate response in self-defense, Iran reserves all options to defend its sovereignty, interest, and people."

Saudi regulatory authorities said Sunday that "no radioactive effects were detected" in the Gulf region after US strikes on Iran's nuclear facilities.

"No radioactive effects were detected on the environment of the Kingdom and the Arab Gulf states as a result of the American military targeting of Iran's nuclear facilities," the kingdom's Nuclear and Radiological Regulatory Commission wrote in a post on X.

Iranian authorities said Sunday "no signs of contamination" after the US attacks on key nuclear sites in several parts of the country.

"No signs of contamination have been recorded," according to National Centre for the Nuclear Safety System, which operates under Iran's Atomic Energy Organization.

"There is therefore no danger for the inhabitants living around the ... sites."

Prime Minister Benjamin Netanyahu said Sunday that his promise to destroy Iran's nuclear facilities had been "fulfilled" following strikes carried out "in perfect coordination" between the Israeli and US militaries.

"From the beginning of the operation, I promised you that Iran's nuclear facilities would be destroyed, one way or another. This promise has been fulfilled," Netanyahu said in a video message posted to social media.

"A short while ago, in perfect coordination between me and President (Donald) Trump, and in perfect operational coordination between the (Israeli forces) and the US military, the United States attacked Iran's three nuclear facilities (at) Fordo, Natanz and Isfahan," he added.

Palestinian militant group Hamas condemned "blatant US aggression" against Iran after President Donald Trump said American warplanes bombed Tehran's main nuclear enrichment facilities.

"The Islamic Resistance Movement (Hamas) condemns in the strongest terms the blatant US aggression against the territory and sovereignty of the Islamic Republic of Iran," the group said in a statement issued after Trump announced the United States had joined Israel's bombing campaign against Iran.

"This brutal aggression is a dangerous escalation," the Hamas statement added, calling the attack "a flagrant violation of international law, and a direct threat to international peace and security".

Israel has closed its airspace until further notice "due to recent developments", the Israel Airports Authority announced on Sunday morning following the US bombing of Iran.

"The airspace of the State of Israel is closed to entry and exit due to recent developments," the authority said in a statement, specifying that "land crossing points (with Egypt) and Jordan are operating normally".

Israel had initially closed its airspace on June 13 after launching the bombing campaign against Iran but reopened it on Friday for flights repatriating Israeli citizens stranded abroad.

President Donald Trump on Saturday warned Iran to not respond after US strikes targeted its main nuclear enrichment facilities in attacks he called a "spectacular military success."

"Any retaliation by Iran against the United States of America will be met with force far greater than what was witnessed tonight," Trump posted on social media after making an address to the nation from the White House.

Iranian authorities said Sunday there was "no danger" to residents in the city of Qom, south of Tehran, following the US attack on a nearby mountain-buried nuclear enrichment site.

"There is no danger to the people of Qom and the surrounding area" around the Fordo nuclear enrichment site, said the province crisis management department in a statement, according to the official IRNA news agency.

Israeli Prime Minister Benjamin Netanyahu congratulated Donald Trump on Sunday after the president said the US military bombed three nuclear sites in Iran.

"Congratulations President Trump. Your bold decision to target Iran's nuclear facilities with the awesome and righteous might of the United States will change history," Netanyahu said in a video message, adding that the attacks demonstrated "America has been truly unsurpassed."

Netanyahu added that Trump had created a "pivot of history" that will "help lead the Middle East and beyond to a future of prosperity and peace".

President Donald Trump that US air strikes had "completely and totally obliterated" Iran's nuclear enrichment facilities and threatened more attacks if Tehran does not make peace.

"There will be either peace or there will be tragedy for Iran far greater than we have witnessed over the last eight days. Remember there are many targets left," Trump said in a late-night address to the nation.

"If peace does not come quickly, we will go after those other targets with precision, speed and skill."

Iran's atomic agency said on Sunday that the country will carry on with its nuclear activities despite the US attacks on key facilities.

"The Atomic Energy Organization of Iran assures the great nation of Iran that despite the evil plots of its enemies ... it will not let the path of development of this national industry (nuclear), which is the result of the blood of nuclear martyrs, be stopped," the organisation said in a statement published by state media.

UN Secretary-General Antonio Guterres voiced concern Saturday at strikes carried out by the United States on Iran nuclear sites, calling them a "dangerous escalation in a region already on the edge."

"At this perilous hour, it is critical to avoid a spiral of chaos," Guterres said in a statement. "There is no military solution. The only path forward is diplomacy. The only hope is peace."

Iran's atomic energy organisation condemned Sunday the US attacks on key nuclear sites including the mountain-buried Fordo as "barbaric" and in violation of international law.

"At dawn today, the country's nuclear sites in Fordo, Natanz and Isfahan were attacked by the enemies of Islamic Iran in a barbaric act that violates international law," the organisation said in a statement published on state media.

Israel has raised its alert level, permitting only essential activities until further notice, the military announced on Sunday after US strikes on Iran.

"It was decided to shift all areas of the country from Partial and Limited Activity to Essential Activity," including "a prohibition on educational activities, gatherings, and workplaces, except for essential sectors", the Israeli military statement said.

President Donald Trump spoke to Israeli Prime Minister Benjamin Netanyahu after the US military launched strikes on three Iranian nuclear facilities, a senior White House official said Saturday.

The United States also "gave Israel a heads-up before the strikes," the official told AFP on condition of anonymity, as Washington joined Israel's air campaign against Iran.

Iranian media said on Sunday that part of the Fordo uranium enrichment facility as well as the Isfahan and Natanz nuclear sites were attacked, after Donald Trump said the US had bombed them.

"A few hours ago, after Qom's air defenses were activated and hostile targets were identified, part of the Fordo nuclear site was attacked by enemy airstrikes," Tasnim news agency reported, quoting Morteza Heydari, spokesperson for the Qom Provincial crisis management department.

Separately, Fars news agency said: "The air defenses of Isfahan and Kashan began to work to counter hostile targets, and several explosions were heard simultaneously."

The US military struck three sites in Iran early Sunday, directly joining Israel ’s war aimed at decapitating the country’s nuclear program in a risky gambit to weaken a longtime foe amid Tehran’s threat of reprisals that could spark a wider regional conflict.

President Donald Trump was the first to disclose the strikes. There was no immediate acknowledgment from the Iranian government. Iran’s state-run IRNA news agency reported that attacks targeted the country’s Fordo, Isfahan and Natanz nuclear sites. The agency did not elaborate.

“We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan," Trump said in a post on social media. "All planes are now outside of Iran air space. A full payload of BOMBS was dropped on the primary site, Fordow. All planes are safely on their way home.”

Trump added in a later post that he would address the nation at 10 p.m. Eastern time, writing “This is an HISTORIC MOMENT FOR THE UNITED STATES OF AMERICA, ISRAEL, AND THE WORLD. IRAN MUST NOW AGREE TO END THIS WAR. THANK YOU!”
