Key events

Tehran residents had reported two rounds of explosions by 10.30am focussed on the Pasteur area of the capital where the presidential office is situated along with the offices of the national security council. Wounded were being taken away in ambulances
Attacks were also mounted on the offices of the supreme leader and the assembly of experts, the body that chooses the Iranian supreme leader. The aim appeared to be to try to damage the political leadership of Iran. Iranian sources said the supreme leader Ayatollah Ali Khamenei was not in Tehran but in a safe undisclosed location.
No assassination of any official was confirmed, despite rumours that the president, Masud Pezeshkhian, had been targeted.
The headquarters of the Islamic Revolutionary Guards Corps was also attacked and a significant number of deaths and injuries were being reported.
But explosions were being reported across the country including in Qom, Tabriz Kermanshah Lorestan Khorramabad and Karaj.
Cyber attacks were also underway and Iranian residents reported that the internet was slowing making reporting of what is happening harder.
Ebrahim Azizi, the chairman of the parliament’s national security commission, wrote on X: “We warned you, but now you have started down a path that is beyond your control.”
Iranian officials vowed a crushing response and seemed to believe this was the start of a full scale military exchange, and not a limited US action designed to force Iran to change its negotiating position.
Iran has also closed its airspace and issued advice to civilians on how to avoid bombings. It is not clear if the Tehran underground systems will be opened as shelters.
Schools and workplaces closed in Jerusalem until Monday
Authorities in Jerusalem have ordered schools and workplaces to remain shut until Monday with people urged to avoid going out unless they are an essential worker.
The home front command in Jerusalem, a regional district of the Israel Defence Forces (IDF) responsible for emergencies, said: “There will be no educational activities, no gatherings, and no going to work, except for workers defined as essential. This policy is in effect from Saturday (2/28) at 8am (6am GMT) until Monday (3/2) at 8pm (6pm GMT).”
‘We are going to raze their missile industry to the ground’ – Trump
Here are some more lines from Trump’s statement on Truth Social.
The United States military has undertaken a massive and ongoing operation to prevent this very wicked, radical dictatorship from threatening America and our core national security interests. We are going to destroy their missiles and raze their missile industry to the ground. It will be totally, again, obliterated. We are going to annihilate their navy. We are going to ensure that the region’s terrorist proxies can no longer destabilise the region or the world, and attack our forces, and no longer use their IEDs – or roadside bombs, as they are sometimes called – to so gravely wound and kill thousands and thousands of people including many Americans. And we will ensure that Iran does not obtain a nuclear weapon.
Lay down your arms or ‘face certain death’, Trump tells Revolutionary Guards
In a video posted on Truth Social, Trump has told the Revolutionary Guards to lay down their arms, saying: “You will be treated fairly with total immunity or you will face certain death.”
Trump has accused Iran of developing long-range missiles that threaten the US and others.
He said the US will “raze their missile industry to the ground” and “annihilate their navy”.

Sirens sounded across Israel just after 8am on Saturday, waking up anyone who was still asleep, and alerting the population that another war had begun.
Less than a year after Israel’s last war with Iran, which involved ballistic missile strikes on towns and cities across the country, citizens were warned to stay near shelters and be alert to air-raid warnings.
Air space was closed, with civilian flights cancelled and travellers turned away from the main Ben Gurion airport.
Saturday is a quiet day in Israel, when observant Jews avoid using phones and transport, and most shops and businesses are closed, so the disruptions caused by war were less immediately obvious.
But schools and universities will be closed on Sunday and Monday, and the large Sheba medical centre near Tel Aviv announced it would shift patients to underground wards.
Mobile phone services cut in Iran
Mobile phone services have been cut in Iran after the Israeli attacks, according to a report from Associated Press.
Blasts heard in several cities – reports
Blasts have been heard in several cities, including the capital, Tehran, and Isfahan in central Iran.
Reuters reports there are long queues at petrol stations in the capital, as many people try to leave. An unnamed Iranian official who spoke to the news agency said several ministries in southern Tehran had been targeted.

The Iraq transport ministry said on Saturday it has also closed national airspace after Israel launched what its defence minister described as a pre-emptive attack against Iran, the state news agency said.
Iran closes its airspace
Iran has closed its airspace until further notice, the civil aviation authority has said, according to a report from Agence France-Presse.
Israel closed its airspace to civilian flights on Saturday after announcing “preventive strikes” on Iran and sounding sirens in Jerusalem.
“Following the security developments, the Minister of Transportation has ordered the Director of the Israel Civil Aviation Authority to close the airspace of the State of Israel to civilian flights,” the minister, Miri Regev, announced.
Reports are emerging that the US is involved in Israel’s strikes on Iran’s capital.
Associated Press reported that a US official and a person familiar with the operation said the US is participating in the Israeli strikes. They spoke on condition of anonymity, AP said.
Reuters has also cited an unnamed Israeli defence official as saying the Israeli operation in Iran was coordinated with the US.
The Guardian has been unable to confirm this.
Ayatollah Ali Khamenei is not in Tehran
Iran’s supreme leader, Ayatollah Ali Khamenei, is not in Tehran and has been transferred to a secure location, an official told Reuters on Saturday.
Israel said it launched a pre-emptive attack against Iran on Saturday, with multiple explosions reported in Tehran.
Loud blasts and columns of smoke in Tehran, report AFP journalists
Two loud blasts were heard in Tehran on Saturday morning by Agence France-Presse journalists, and two plumes of thick smoke were seen over the centre and east of the Iranian capital.
“The type of explosions suggests that this is a missile attack,” the Fars news agency reported, without immediately providing further details.
Israel strikes Iran
Israel says it has launched a “preventative” strike on Iran and is preparing for retaliation.
On Friday, Donald Trump said he had not made a final decision on whether to launch US strikes on Iran, but added he was “not happy” with the situation, and that military force, including regime change, remained an option.
Talks between the US and Iran on Tehran’s nuclear programme ended inconclusively, with a suggestion that further discussions would be held next week.
It comes amid a large buildup of US naval forces in the Middle East, including repositioning aircraft carriers and other warships.
Trump had previously given Tehran a deadline of 10 to 15 days to make a deal to resolve their longstanding nuclear dispute or face “really bad things”.
It came as Iran accused the US of spreading “big lies” about its missiles programme, after Trump claimed Tehran was building weapons that could strike the US.
During his State of the Union speech, the US president said Iran has “already developed missiles that can threaten Europe and our bases overseas, and they’re working to build missiles that will soon reach” the US.
He described Iran as “the world’s number one sponsor of terror” and claimed at least 32,000 protesters were killed during recent unrest in the country.
The Iranian foreign ministry spokesperson, Esmail Baqaei, rejected those claims, without mentioning Trump directly. “Whatever they’re alleging in regards to Iran’s nuclear programme, Iran’s ballistic missiles, and the number of casualties during January’s unrest, is simply the repetition of ‘big lies’,” he posted on X.
