More now on the latest Iranian attack targeting Israel in the last hour.
The Israeli Defence Forces has shared an update, saying that Iran launched "several missiles".
The IDF adds "most of them were intercepted".
It continued to instruct Israeli citizens and members of the public to "follow the instructions of the Home Front Command".
The Home Front Commander later added the public could leave their protected spaces.
Seyed Ali Mousavi, the Iranian ambassador to the UK, is taking questions from the cross-party Foreign Affairs select committee in Parliament.
Israel's ambassador to the UK is not appearing because she was "unavailable", committee chair Dame Emily Thornberry says as the session starts.

Iran has launched missiles towards Israel, according to the Israeli Defence Forces.
Air raid sirens have sounded in Tel Aviv and several areas across the country.
The Israeli Air Force is working to intercept the threat, the IDF added.
Four people were injured on their way to shelters, Magen David Adom, the Israeli emergency services, said.
Earlier today, Iran claimed it had struck a major blow against Israel - by hitting a Mossad operations centre (see our 10.20 post).
The Israeli intelligence agency has been a key part of Israeli operations at home and abroad since the Jewish state declared independence in 1948.
Even for this latest conflict, which Israel began when it attacked Iran last Friday, the spy agency was reportedly at the heart of the mission.
That's because, it is said, Mossad commandos gathered intelligence over a number of years by infiltrating deep into Iran - information which informed the strikes.
But Mossad operatives also reportedly played a part in the attacks themselves to destroy weapons systems and other Israeli targets in Iran.
It's the latest in a series of daring Mossad operations throughout Israel's history.
The agency is particularly famous for the 1960 capture of former Nazi official Adolf Eichmann, one of the major organisers of the Holocaust.
And it was back in the headlines last year, following the deadly pager explosions which wiped out many of Hezbollah's leaders in Lebanon.
While Mossad's exploits are known in some limited detail, Israel maintains a policy of ambiguity around its operations.

Here's what we do know for sure...
In Hebrew, Mossad simply means institute, and its full name is the Institute for Intelligence and Special Operations.
In its mission statement, Mossad says its aims include:
It is, in short, the Israeli equivalent of the UK's Secret Intelligence Service (better known as MI6) or the CIA in the US.
Unlike these Western intelligence agencies, however, the Mossad is veiled in more secrecy and often takes a much more proactive role against Israel's enemies.
The Mossad is overseen directly by the Israeli prime minister's office.
It doesn't list the address of its headquarters or any telephone numbers, which is partly why it is difficult to immediately identify the site Iran said it struck earlier.
It does not even say how many people it employs.
Only the identity of its director can be disclosed under Israeli law.
However, Mossad's website does have a "careers" section for job application forms in Hebrew and English.
Israel's strikes and assassinations have left Iran's supreme leader isolated with "nowhere to go", our military analyst Michael Clarke has said.
Speaking this afternoon on Sky News to presenter Leah Boleto, he said the Israeli bombing campaign had been "very methodical through all the targets that they want".
This, Clarke said, has "isolated Ali Khamenei, he's got almost nobody around him".
He added: "The Israelis know who he depends on, and they've eliminated almost all of them.
"He's got, apart from his son and his deputy intelligence director, very few people around him that he trusts."
'Nowhere to go'
Israel is trying to send a clear message to the Iranian leadership, Clarke adds, which is essentially: "You've got nowhere to go."
He adds: "You are losing and you'll lose badly, and the longer you leave it, the more badly your people will lose."
However, he said this may not force the Iranians to capitulate.
He also reflected on the apparent feeling among the Israelis that they had free rein to go where they liked and "bomb what they want".
"That's the message Israel is sending," Clarke said.
Israel's strikes on western Iran today targeted missile launchers and radars, the Israeli Defence Forces says.
We reported earlier today on explosions heard in Tehran (see 12.12 post) and reports of an Israeli attack (at 11.12).
Now, the IDF has confirmed it conducted "a series of strikes in western Iran".
"As part of the strikes, a number of sites and dozens of surface-to-surface missile launchers were struck," the IDF says.
It adds: "In addition, since the morning, the Israeli Air Force conducted intelligence-based strikes on surface-to-air missile launch sites and radars embedded in western Iran."
Donald Trump has been busy on the global stage today - here's a reminder of what he's been saying about the Israel-Iran conflict.
'Evacuate Tehran!'
The US president seemingly issued a warning to residents in Tehran shortly before midnight in the UK last night, saying: "Everyone should immediately evacuate Tehran!"
Trump has pinned his warning to the residents of Iran's capital to the top of his Truth Social profile today.
Trump leaves G7 early - and dismisses Macron's explanation
Trump went on to leave the G7 summit of world leaders in Canada early.
After he left, French President Emmanuel Macron said he thought it was because Trump was going to work on peace negotiations in the Middle East - something Trump took issue with.
Trump, again writing on his own social media platform Truth Social, said: "Publicity seeking President Emmanuel Macron, of France, mistakenly said that I left the G7 Summit, in Canada, to go back to D.C. to work on a 'cease fire' between Israel and Iran.
"Wrong!
"He has no idea why I am now on my way to Washington, but it certainly has nothing to do with a Cease Fire.
"Much bigger than that."
'Gloves are off'
The US leader also spoke to reporters aboard Air Force One, as he flew back to Washington DC.
Trump said he wanted a "real end" to the conflict, "not a ceasefire", and warned that if US troops were harmed by Iran, then the "gloves are off".
'They know how to reach me'
Then, shortly before midday in the UK, Trump was quick to point out he hadn't reached out to Iran for peace talks, instead saying: "If they want to talk, they know how to reach me."
Israel's airstrikes may have hit and damaged one of Iran's key enrichment sites, according to the UN nuclear watchdog.
The International Atomic Energy Agency has said today it believes the Natanz facility's centrifuge halls may have had "direct impacts".
That's the first time the UN group has assessed damage in the underground parts of Natanz, which is the main enrichment facility of Iran's nuclear program.
"Based on continued analysis of high-resolution satellite imagery collected after Friday's attacks, the IAEA has identified additional elements that indicate direct impacts on the underground enrichment halls at Natanz," said the agency.
An above-ground enrichment hall had been destroyed already, as well as electrical equipment powering the facility.
Israel's stated goal is to prevent Iran from developing a nuclear weapon, and so-called "bunker busters" could be one way of damaging hard-to-reach nuclear sites - see our 13.32 post for more on that.
The Iranian leadership is "on the run", an Israeli military official has claimed, according to the Reuters news agency.
The official, who was not named and speaking to Reuters on the condition of anonymity, said that Israel struck dozens of targets linked to Iran's nuclear and missile programmes last night.
The Reuters source added that while Israel had not targeted the underground Fordow nuclear facility in Iran yet, such a strike could still happen.
We reported in our previous post on how the facility would likely need so-called "bunker busting" bombs to damage it significantly - which only the US has.
Iran has so far fired 400 ballistic missiles and hundreds of drones towards Israel, the Israeli official also told Reuters.
Israel's number one goal in launching strikes on Iran appears to be destroying its potential to create a nuclear weapon.
One of Iran's key nuclear sites, the Fordow nuclear fuel enrichment plant, is deep underground in a mountain.
If the US decides to support Israel more directly in its attacks on Iran, one option could be to provide "bunker buster" bombs.
Such a bomb, which Israel doesn't currently possess the means to use, could penetrate deep enough to damage such a facility and help destroy Tehran's nuclear capabilities.
What is a bunker buster bomb?
"Bunker buster" is a broad term to describe bombs designed to penetrate deep below the surface before detonating.
The latest in the US arsenal is the GBU-57 A/B Massive Ordnance Penetrator bomb.
It is a roughly 13,600kg precision-guided bomb, according to the US Air Force, and is believed to be able to penetrate 61m (200ft) deep before exploding.
Multiple bombs can be dropped one after the other, effectively drilling deeper and deeper into the ground.
Iran's nuclear mountain base
Fordow is Iran's second nuclear enrichment facility after Natanz, its main facility.
So far, Israeli strikes aren't believed to have seriously damaged Natanz's underground areas.
Fordow is smaller than Natanz and is built into the side of a mountain near the city of Qom, around 60 miles southwest of Tehran.
It is an estimated 80 metres under rock and soil and reportedly protected by Iranian and Russian surface-to-air missile systems.
These may have been struck during the Israeli campaign so far.

Israel's goal could be to 'eliminate' Fordow site
Prime Minister Benjamin Netanyahu has said the goal of attacking Iran was to eliminate its nuclear and missile programme, and Israeli officials have said Fordow is part of that plan.
"This entire operation... really has to be completed with the elimination of Fordow," Yechiel Leiter, Israel's ambassador to the US, told Fox News on Friday.
So watch out for more discussions of "bunker busters" if the attacks on Fordow escalate - and read more in our explainer below:
