Watch: How successful have the US strikes on Iran been?
Trump confirms the US struck Iran's nuclear facilities at Fordo, Natanz, and Isfahan a short while ago.
"Everyone heard those names for years as they built this horrible destructive enterprise," he says.
"Tonight I can report to the world that the strikes were a spectacular military success."
He goes on to say "Iran’s key nuclear enrichment facilities have been completely and totally obliterated".
Iran "must now make peace," says US President Donald Trump.
"If they do not, future attacks will be far greater and a lot easier," he says.

US House Minority Leader Hakeem Jeffries says that US strikes on Iran has "dramatically increased" the risk of war.
In a post on X, Jeffries says: "President Trump misled the country about his intentions, failed to seek congressional authorisation for the use of military force and risks the entanglement in a potentially disastrous war in the Middle East."
He added that Trump "shoulders complete and total responsibility for any adverse consequences that flow from his unilateral military action".
Separately, Democratic US senator Bernie Sanders says that Trump's strikes are "grossly unconstitutional".
"The only entity that can take this country to war is the US Congress. The president does not have the right," Sanders added.

"President Trump and I often say: 'Peace through strength.' First comes strength, then comes peace," he says.
"And tonight, president Trump and the United States acted with a lot of strength," Netanyahu says.
As we've reported earlier, the US had given Israel a heads up ahead of the strikes. Netanayhu and Trump also spoke afterwards.

Israel has always maintained that it had the capacity to destroy Iran’s nuclear programme on its own, but it is also no secret that only America possessed the massive ordnance capable of dealing with the strongest levels of protection, particularly at Fordo, built deep inside a mountain.
If the sites are now indeed out of use, then there may be an opportunity for Israel’s Prime Minister Benjamin Netanyahu to declare his main war aim complete.
But this morning the Middle East will be holding its breath, waiting to see whether this marks the beginning of the end of this conflict, or the beginning of an even more deadly phase to the war.
Last week Iran’s Supreme Leader Ali Khamenei had vowed to hit back at the US were it to enter the war. “The Americans should know that any US military intervention will undoubtedly be accompanied by irreparable damage,” he said.
Only on Saturday the Houthi group in Yemen - staunch Iranian allies - had threatened to attack US ships transiting through the Red Sea if America entered the war.

As we have reported, one of the main targets of the US strikes was the Fordo nuclear facility.
This is what the area looks like.
They were reported to have used 'bunker-buster' bombs.
And the only planes that could carry such bombs are B-2 stealth bombers.
US President Donald Trump and Israeli President Benjamin Netanyahu spoke after the US strikes on Iran's nuclear facilities, the BBC's US partner CBS News reported, citing a senior White House official.
The US gave Israel a heads up before the strikes, the source told CBS.
Senior Department of Defense officials also confirmed that the GBU-57A Massive Ordnance Penetrator, a "bunker buster" bomb, was used in the attack, with two being deployed for each of the nuclear targets.
As we have reported, the three sites targeted by the US tonight were Fordo, Natanz and Esfahan.

The question following the US strikes on Iran is now what the reaction from Tehran will be.
This is a seismic moment in the war and the relationship between Iran and Israel.
It carries potentially huge implications for American security. There are around 40,000 American troops stationed in this region. They will be on extremely high alert.
Yesterday, the Iran-backed Houthis in Yemen threatened that they would resume attacks on American ships in the Red Sea if the US got militarily involved in Iran.
There will be now a huge fear of Iranian retaliation on American and military assets in the region, and of course of how Iran will retaliate towards Israel.
More details are emerging about the diplomacy leading up to the strikes.
The US reached out to Iran "diplomatically" on Saturday to say the strikes are all it plans to do and that "regime change efforts are not planned", according to the BBC's US partner CBS News.
Earlier this week, several US officials told CBS that Trump opposed a plan to kill Iran's supreme leader Ayatollah Ali Khamenei.

Here in Washington, the news of the US strikes in Iran set off a mad scramble across the city to follow the news, with reactions coming in quickly.
US politicians quickly weighed in on the news.
"This is not constitutional," wrote Republican Thomas Massie of Kentucky - a noted isolationist who has for days been warning that he believes US military involvement runs counter to Trump's "America First" agenda.
John Fetterman, a Democratic Senator from Pennsylvania - and vocal backer of Israel - wrote on X that "as I've long maintained, this was the correct move by POTUS [President of the US]."
"Iran is the world's leading sponsor of terrorism and cannot have nuclear capabilities," he added.

The Israel Defense Forces has just issued a statement, stepping up the state of alert.
"With the approval of the Minister of Defense Israel Katz, and following the situational assessment, it was determined that as of today (Sunday), at 03:45am, (01:45am BST) immediate changes will be made to the Home Front Command instructions.
"As part of the changes, it was decided to shift all areas of the country from Partial and Limited Activity to Essential Activity. The instructions include: a prohibition on educational activities, gatherings, and workplaces, except for essential sectors."
The IDF adds that the public is required to follow the instructions published on the official Home Front Command channels.
We're now getting some initial reaction from US lawmakers on Trump's surprise announcement of strikes against Iran.
South Carolina Senator Lindsey Graham congratulates Trump and says he "made the right call".
He adds that Iran's "regime deserves it".
Republican Senator Roger Wicker echoes the praise, saying Trump made a "deliberate" and "correct" decision to eliminate the "existential threat" posed by Iran.
But there is also criticism from some, with Republican Senator Thomas Massie of Kentucky saying "this is not Constitutional".
Sara Jacobs, a Democratic representative of California, says the strikes are "an escalation that risks bringing the US into another endless and deadly war”.
Secretary of State Marco Rubio has reposted Trump's Truth Social announcement but has yet to publicly comment on the strikes.

Akbar Salehi, the security deputy governor of Isfahan, has just said: "Several explosions were heard in Natanz and Isfahan, we saw attacks near the nuclear sites of Isfahan and Natanz."
All three strike sites mentioned by Trump have now been confirmed by Iranian officials.

Iran has been vocal in its threat to strike US bases in the Middle East if it were to be attacked.
US stations around 40,000 troops in the region. Not only Iran, but one of its proxies in the region, the Houthi rebels in Yemen has said it will strike American ships that are passing through the Suez canal down the Red Sea.
Though President Trump had called on Iran to "end this war", this war might just be starting.

We have just seen the first official acknowledgment of the Fordo bombing from an Iranian official.
Morteza Heydari, spokesperson of the Qom Province Crisis Management, says "a part of the Fordo nuclear site area came under an aerial attack", according to the Tasnim news agency.

“Two weeks” turned out to be two days.
On Thursday Donald Trump gave the Iranians a deadline if they wanted to avoid a US strike on its nuclear facilities, but that deadline turned out to be much shorter than expected.
In his Truth Social post announcing what he said were successful US strikes on three Iran nuclear sites, the American president concluded by writing “now is the time for peace”.
That may be an optimistic outlook, however. Iran had warned of reprisals if the US joined Israel in attacking its sovereign territory. And while the Israelis have made considerable efforts toward degrading Iran’s military capabilities, the Ayatollah still has weapons at his disposal.
Things could get messy fast.

We have now got our first reaction from Iran.
The deputy political director of Iran’s state broadcaster, Hassan Abedini, has appeared live on state TV just now.
He says Iran evacuated these three nuclear sites a “while ago”.
He also says that even if what Trump says is true, Iran “didn’t suffer a major blow because the materials had already been taken out”.
Israel was in "full coordination" with the US for its strikes on Iran's nuclear facilities, an Israeli official told Israeli public broadcaster Kan, according to the Reuters news agency.
