Israel attacks Iran LIVE: Latest updates as strikes reported in city that hosts nuclear programme and flights are diverted after Netanyahu ignored Biden's plea for calm

Israel's national security minister has taken to X to write just the word 'feeble' after the alleged Israeli strike on Iran.

Itamar Ben Gvir has been the leader of the far-right party Jewish Power since 2019, and also controls Israel's Border Police division in the occupied West Bank.

He has previously said: 'In order to establish deterrence in the Middle East, you must show them that you've gone berserk and completely lost it.'

Following the Iranian attack on Saturday he also wrote on X: 'We need a crushing attack.'

The foreign secretary met with the Israeli PM on Wednesday where he urged him to do a little as possible to escalate the situation with Iran further.

Lord Cameron, speaking after meeting Netanyahu, said he hoped that 'anything Israel does is as limited and as targeted and as smart as possible.

'It’s in no one’s interest that we see escalation and that is what we said very clearly to all the people I’ve been speaking to here in Israel.'

This morning the Prime Minister's office has claimed that Israel has a right to self-defence, but added 'we have been stressing to Israelis that what matters now is de-escalation'.

It comes after the Foreign Office lead sanctions against Iran following its attack on Saturday.

It wrote on X: 'Iran’s attack on a sovereign state was dangerous and reckless. Co-ordinated with the USA, we are sanctioning leading Iranian military figures and entities involved in the attacks against Israel and tightening the net on key actors within Iran’s drones and missile industries.'

Ships in the Arabian Gulf and the Western Indian Ocean have been told to stay alert this morning, a British security firm has said.

Ambrey reported merchant vessels travelling across the surrounding waters had been given a warning of increased drone activity in the region.

The International Atomic Energy Agency has confrimed that there has been no damage to Iran's nuclear sites during this morning's alleged attack by Israel.

The UN nuclear watchdog said it is monitoring the situation 'very closely' and calls for 'extreme restraint'.

Iran has hinted it could build a nuclear weapon if Benjamin Netanyahu strikes Tehran's atomic sites - and target Israel's own nuclear facilities in response.

A senior Revolutionary Guards general said Iran could review its 'nuclear doctrine' in the event of an Israeli strike on Tehran's atomic facilities.

The comments represent the first time Iran has explicitly mentioned its suspected nuclear weapons programme since Tehran's unprecedented weekend attack that saw Iran launch more than 300 missiles at Israel.

It was in retaliation for an April 1 air strike on the Iranian consulate in Damascus that killed 13 people, including two generals.

Unconfirmed footage circulating social media appear to show explosions overhead in Iran, however MailOnline has not been able to confirm the footage.

Shortly after reports of strikes emerged, three drones were 'successfully shot down by the country's air defense', according to Iran's National Cyberspace Center spokesman Hossein Dalirain on X.

Iran threatened to use 'weapons it has never used' if Israel struck, and Iranian Foreign Minister Hossein Amir-Abdollahian also cautioned that Iran would strike back at the 'maximum level' if Israel fired.

'In case the Israeli regime embarks on adventurism again and takes action against the interests of Iran, the next response from us will be immediate and at a maximum level,' Amir-Abdollahian told CNN.

Biden had warned Israel not to retaliate to Saturday's strikes and urged Israeli Prime Minister Benjamin Netanyahu to 'take the win' of the foiled Iranian attack.

But the Israeli leader brushed off Biden's warnings, insisting Israel would 'make its own decisions' in how to react to Iran's attack.

Israeli officials warned the Biden administration of its intent to strike before launching in previous days, but an official told CNN that the US did not 'green light' any Israeli response.

US Defense Secretary Lloyd Austin spoke with his Israeli counterpart Yoav Gallant on Thursday afternoon, but a senior source declined to confirm to the New York Times if Gallant warned about the strikes that hit hours after the meeting.

Israeli military officials have reportedly stressed that today's strikes were a 'limited response' to Iran's attack, appearing to target military hubs used by Iran in their onslaught on Saturday.

Iran closed its airports in Tehran, Shiraz and Isfahan after the attack and cleared flights from the western portion of its airspace for a few hours after the attack, according to flight tracking website FlightRadar24.

By 0445 GMT the airports and airspace had reopened, and closure notices posted on a U.S. Federal Aviation Administration database had been removed.

Before the airports reopened, Flydubai said it had cancelled its Friday flights to Iran. One of its earlier flights turned back to Dubai, it said.

An Iran Air flight from Rome to Tehran was diverted to Ankara, Turkey, Flightradar 24 showed.

Emirates, Flydubai, Turkish Air, Wizz Air Abu Dhabi and Belavia were among the carriers continuing to fly over the part of Iran's airspace that remained open in the initial hours after the attack early on Friday, the tracking website showed.

'We are monitoring the situation closely and will make changes to our flight paths in consultation with the relevant authorities,' Flydubai said in a statement.

Iran sought to downplay any significant damage to its military facilities and outright denied any nuclear plants were destroyed, claiming that 'so far, no large-scale strikes or explosions by any air threat have been reported.'

Reports citing senior US military sources contradicted this and claimed that targets were hit. No official comment has been released by either Israel, Iran or the US.

Israel has conducted strikes on a target in Iran, defying President Joe Biden's warnings over plunging the Middle East further into conflict.

US officials confirmed strikes hit a site in Iran, however it is unclear what exact target was hit or the extent of the damage.

Officials say the city of Isfahan in central Iran was struck at 5am local time. The city hosts one of Iran's nuclear facilities, although US military sources reportedly said the target was not believed to be nuclear.
