The BBC News channel is now putting some of the most searched questions on the US-Israel war with Iran to our panel of experts and correspondents.

You can watch live at the top of the page.

The Israel Defense Forces says its large-scale wave of strikes on Iranian infrastructure in Tehran, which we reported about just over an hour ago, has now concluded.

In an update on the messaging app Telegram, it says it attacked infrastructure and "sites used by the [Iranian] regime to produce weapons", saying there was an "emphasis on ballistic missile production sites".

While these attacks were in progress, the IDF says it carried out simultaneous attacks in Iran's city of Isfahan, which is approximately 435km (270 miles) away.

These attacks, the IDF says, targeted ballistic missile systems, including launchers and missile storage sites intended for use against Israel.

Our panel of experts and correspondents are preparing to answer some of the most searched questions on the US-Israeli war with Iran.

The panel will feature BBC chief international correspondent Lyse Doucet, business editor Simon Jack, experts from BBC Persian and chief presenter Sumi Somaskanda, who will be reporting from the White House.

We'll be addressing what's happening on the ground in Iran and the implications for travel, oil prices and economies around the world.

Tucked within the snowy mountains at the Kapikoy border crossing, suitcases are being wheeled in both directions.

Those emerging from Iran often talk about the heavy bombardments they’re trying to escape. One woman, in her twenties, claimed she’d never seen the regime so fragile, and was hopeful more international support would follow.

“If this military action helps topple the government, maybe it’s a good idea,” says Ede, who protested against the authorities at the start of the year. He saw dozens of people killed by masked security forces.

“If this is just about bombardment, maybe not; I’m no politician though,” he adds.

We meet Emir Mohamed heading the other way. He’s moving back to Iran out of concern for his family, and sees Donald Trump’s military intervention as hypocritical, arguing that the US should stay out of Iranian affairs.

We encounter those who are anti-regime, but also against the way the US and Israel have tried to topple it.

I'm at Manchester Airport, where a flight from Dubai landed a short while ago.

Neil Ramchander, who has been stuck in Dubai for the last three days, says the experience was "pretty terrifying" and there was a “huge sense of relief” on the flight home. "We all clapped on arrival," he tells me.

On the way home to Ireland, Rebekah O’Dwyer says it was "a little bit nerve-wracking" getting on the flight. In Dubai, she says: "You could hear all like the sirens and all like the loud kind of noises above us. We didn’t know where to go, where to look."

Kylie Bergman recalls receiving a phone call at 01:30 this morning, where she was told to get on a plane. By 04:00 she was on the move. Getting the call "felt like [she] had won the lottery," she says.

Earlier we reported about video and satellite images showing fire and damage at the Fujairah Oil Terminal in the United Arab Emirates.

We've just seen some more images showing smoke billowing above the oil terminal, which is on the Gulf of Oman coast.

The UAE's Fujairah media office says a fire broke out after debris fell from a drone that had been intercepted by air defences, but it adds the fire has been put out and no injuries reported.

German Chancellor Friedrich Merz is expected to arrive at the White House in a few hours' time to meet with Donald Trump - the US president's first meeting with a foreign leader since strikes began in Iran.

The visit has been long-planned and was announced before the US-Israeli military operation began, but both leaders are now focused on their interests in the Middle East as fighting escalates.

While Germany has neither endorsed or supported the operation, the country has - along with France and the UK - called on Iran's leaders to stop their retaliatory strikes.

In a joint statement on Sunday, those three countries said they would "take steps to defend our interests and those of allies in the region", including, potentially, by "enabling necessary and proportionate defensive action" to destroy Iran's capability to fire drones and missiles.

Trump will likely be hoping that Germany takes those steps and the two leaders will almost certainly discuss Iran's future.

Conflict in the Middle East has caused oil and gas prices to jump, but it may also lead to poorer crop yields and higher food prices if it continues to impact global shipping.

The continued closure of the Strait of Hormuz would lead to higher global prices of staples like corn, wheat and rice because the waterway is vital to shipping one-third of the world's urea - an essential ingredient in fertiliser, the chief executive of Yara has told World Business Express.

"In some crops, you could see reductions [of yields] of up to 50%," said Svein Tore Holsether, who runs the world's second-largest fertiliser company.

The timing of the closure means supply of urea is constrained at a time when farmers and growers are buying fertiliser to apply it to fields, he said.

Iran's ambassador to the United Nations in Geneva, Ali Bahreini, has cast doubt on the prospect of negotiations with the United States.

"For the time being we are very doubtful about the usefulness of negotiation," Ali Bahreini told reporters in Geneva on Tuesday, according to the Reuters news agency.

It comes after US President Trump declared it was "too late" to talk in a post on his Truth Social messaging platform.

I've been speaking to people inside Iran following a new wave of strikes.

Omid, in his twenties, says people are becoming uneasy about how long the situation will go on for.

"I had assumed they would target certain officials like [Iran's former Supreme Leader] Khamenei and that it would be over by now," he says.

"There is a greater security presence on the streets, but the streets themselves are empty. Some shops have closed, particularly those near the affected areas... I heard the sound of explosions today in Tehran just now”.

Pouya, in his thirties, tells me that prices have gone up since the attacks started. The cost of rice and potatoes have increased drastically, he says from Pardis - a city near Tehran.

From the city of Karaj, Shayan says it's very difficult to get online now. "The price of everything has gone up," he says. "I didn’t hear any strikes today; it feels like the calm before the storm," he adds.

Maryam, in her twenties and in northern Tehran, sent me a text to say: "The attacks last night were terrible. Our house was shaking.

"We were preparing to leave the area because our home is near where the IDF [Israel Defense Forces] had issued an evacuation order. Before we could set off, they struck.”

In an update on the messaging app Telegram, the Israel Defense Forces says it has begun a large-scale wave of strikes targeting infrastructure in Iran's capital, Tehran.

It says there will be more details to follow.

The smoke plume in the satellite image is consistent with a verified picture showing part of the port on fire after it was reportedly attacked yesterday.

The picture shows a massive cloud of thick, black smoke above a large area of the port which is on the Gulf of Oman.

A reverse image search shows the picture was first posted online yesterday

The UK has deployed "a significant level of defensive capability" to Cyprus, according to the prime minister's official spokesperson.

Asked to comment on reports the UK may deploy a warship to help protect the UK airbase there, the spokesperson said he "wouldn't get into speculation on force movements or specific operations for reasons of operational security".

It's understood that Downing Street is considering the option but no decision has been taken at this stage.

The spokesperson said "I think we have set out multiple times the assets and capabilities that we have deployed defensively to the region. That includes radar systems, air defence, and F-35 jets. That is a significant level of defensive capability to our bases in Cyprus".

They added "we keep our force protection under constant review. We are not going to provide a running commentary on exact force movements, but the MOD [Ministry of Defence] will provide updates when our forces have taken significant defensive action".

This war is seen by many Israelis as a necessitypublished at 13:33 GMT

With warning sirens regularly going off to tell Israelis to enter air raid shelters, and schools and most businesses closed, it may come as a surprise to see polls indicating strong Israeli public support for military action against Iran.

But this war is seen by many Jewish Israelis as a necessity: an opportunity to deal with an existential threat from Iran and a way to further weaken its regional proxies, notably the Lebanese armed group, Hezbollah, and Palestinian armed groups.

In late February, a survey by Israel’s Channel 12 indicated 59% of Israelis favoured joining a potential strike on Iran. Now a war is under way, it is thought that levels of support are likely to have increased given military successes – particularly the assassination of Iran’s Supreme Leader Ayatollah Ali Khamenei – and the strong coordination between Israel and the US.

Israelis have high confidence in their country’s air defence capabilities. After two years of war in Gaza, many have also developed routines to deal with disruption to their daily lives.

Still, it goes without saying that public sentiment could easily shift if large numbers of Israeli civilians or soldiers are killed - or if this conflict starts to drag on without achieving its goals and a clear exit strategy.

Pakistan says at least 300 Iranian citizens have reached the country, as Israeli and US attacks continue throughout Iran.

Its province of Balochistan borders Iran and was already a turbulent region. It's home to separatist groups and has seen a decades-long insurgency.

Pakistan's leaders are balancing competing relationships right now. Pakistan nominated President Trump for a Nobel Peace Prize last year, as its rapport with the US grew.

But despite being a Sunni-majority country, there are Shia communities across Pakistan, who strongly oppose the war in Iran.

The US embassy in Saudi Arabia is warning of imminent missile and drone attacks over Dhahran, where a US consulate is located.

US citizens are urged to shelter in place and "review security plans in the event of an attack"., external

Dhahran, on Saudi's east coast, is a major centre of the oil industry - and is home to the headquarters of the Saudi national oil firm Aramco.

As we just reported, the UAE says it has intercepted 172 Iranian missiles and 755 drones since Saturday.

Bahrain's military has also issued a statement, saying it has intercepted 73 missiles and 91 drones launched from Iran since Saturday.

A number of Iranian strikes have hit Bahrain, including at a US navy base in the country.

I just asked the spokesperson of Qatar’s foreign ministry for more details about the country's downing of two Iranian fighter jets yesterday.

At a press briefing, Majed al Ansari said the bombers were monitored coming into Qatari airspace and rules of engagement were followed "to the letter".

“The pilots were informed that they had crossed into Qatari airspace and at the moment [it was seen] that they are a definite threat to Doha, that their trajectory was Doha, they were shot down over the waters of the Gulf," he said, noting that there were no updates on the status of the pilots.

When it came to possible retaliation against Iran, Ansari said "all options are with our leadership - but we have to make it very clear that attacks like these will not go unanswered".

The UAE's Ministry of Defence says its air defences have destroyed 172 missiles since Iran launched its strikes in the region, in response to US-Israeli strikes on Tehran.

A spokesperson for the ministry says there have been 186 missiles in total, with 13 of them falling into the sea and one other hitting the UAE's territory.

The ministry detected a further 812 Iranian drones, the spokesperson adds, saying that the UAE managed to intercept 755 of them. Fifty-seven fell on the country.

The UAE also detected and destroyed eight cruise missiles "which caused some collateral damage, as well as resulting in three fatalities and 68 cases of minor injuries," as well as damage to "civilian facilities".

A commercial plane has been seen leaving Beirut airport in Lebanon, as smoke from the city rises into the sky.

Beirut, and parts of southern Lebanon, have been hit by Israeli strikes - in response, Israel says, to attacks from the Lebanon-based militant group, Hezbollah.

Thousands of flights in the Middle East have been cancelled since the beginning of the conflict on Saturday, with airspace closed above many countries in the area.
