A search and rescue mission has rescued a crew member from a US F-15E fighter jet that was downed in southern Iran,US media reports.

What has happened to the second crew member on the jet remains unknown, but CBS reports that the search is ongoing, citing two officials.

It says the rescue crew included two helicopters and an A-10 Warthog plane. It adds one helicopter carrying the rescued pilot from the F-15 jet was hit by small arms fire, injuring crew members on board - but it landed safely.

CBS reports that the A-10 Warthog was hit, with the pilot ejecting over the Gulf and subsequently rescued. Iran's army claims to have shot down an A-10 Warthog, according to state media reports - it's not clear if this is the same plane that CBS was reporting about.

Verified footage appears to show a US plane and two helicopters searching for the fighter jet's crew in the Khuzestan province.

There have also been reports that the Israeli military has held off strikes in the area, while the search operation is being undertaken.

US President Donald Trump told US network NBC "we're in war", and the attack on the fighter jet will not affect any negotiations with Iran.

The search for one missing US service member after a fighter jet came down in Iran is ongoing, according to CBS, the BBC's US partner.

In the US, elite units of the Air Force are specially trained for combat search and rescue (CSAR) missions and are often pre-emptively deployed near conflict areas where aircraft could be lost. It's not clear if these are the forces deployed in this specific search and rescue operation.

Their work is considered part of a broader promise to US service members that they will not be left behind.

The missions are extremely time-sensitive, as enemy forces would likely be deployed in the same area to try and locate the same US personnel the CSAR teams are trying to rescue.

Modern CSAR began during the Vietnam War and required a vast expansion of rescue missions with increased scope and complexity.

The experience helped the military refine tactics and procedures that have helped form the foundation of rescue operations since.

With the US-Israeli war with Iran waging on, the White House earlier announced that it will ask the US Congress to approve $1.5tn (£1.13tn) defence budget for the 2027 fiscal year - a record-breaking 42% increase from the year before.

If approved and enacted by Congress, the budget would be the highest in modern US history.

Trump's move to up defence spending, however, pre-dates the beginning of the current conflict in Iran, and is reflective of the Trump administration's focus on domestic production and high-profile projects.

This includes funding his proposed Golden Dome missile defence system, which is aimed at protecting the US from next-generation aerial threats.

An outline of the budget shared by the Office of Management and Budget notes that the request would cover dozen of military ships, including a new series of heavily armed US Navy Trump-class battleships that the US president unveiled in December.

The request is separate from one made in March that was specifically tied to the war in Iran, in which the Pentagon proposed $200bn to support the ongoing Operation Epic Fury and to backfill munitions and supplies.

I've spoken to two military analysts who say that while a US fighter jet being shot down over Iran is operationally not very significant, it could further galvanise the American public against the war.

"For people who have been arguing from the start that this war was a mistake, that this war was an unnecessary risk to US service members, it was an unnecessary use of US military power and a waste of US military resources - this is just the exclamation point on that argument," says Jennifer Kavanagh, a senior fellow and director of military analysis at the think tank Defense Priorities, which advocates for restraint in US foreign policy.

She says the incident makes walking away from the war now, at least in the immediate term, "essentially impossible politically for Trump".

That's because, she says, the US president needs something else to further underline his claims of victory and "this is not it".

James Jeffrey, a military strategy expert and fellow at think tank The Washington Institute, says most Americans would say right now this incident makes them more upset about the war.

"This is really a concern because that's how they feel," Jeffrey says. "Americans love their service people, more than most modern countries do."

But, he says, public concern won't affect how Trump handles the war, or what steps he decides to take next.

President Donald Trump says the downing of a US fighter jet would not impact any negotiations with Iran to end the war, according to NBC News.

It says in a brief phone interview the president was asked if today’s events would have an impact. He replied: "No, not at all. No, it’s war. We’re in war."

Fallout from this incident is worse than initially thought for the USpublished at 21:28 BST

According to CBS reporting, citing two US officials, the fallout from this incident is worse than initially thought.

Not only did they say an F-15E was shot down this morning, but an A-10 Warthog aircraft that was part of the search and rescue mission for the downed jet was also shot and damaged.

The pilot from that ejected and was successfully recovered.

Two helicopters also took part in the rescue mission and retrieved the F-15E pilot who had ejected, but the search is continuing for the second crew member.

The helicopter carrying the rescued pilot was then hit by small arms fire, wounding crew members on board.

All of this indicates that, despite Donald Trump’s recent claims that there is nothing Iran can do about US aircraft in its skies - the dangers still very much exist.

I'm hearing that there have been heavy explosions in east Tehran from two sources.

Three others say they're hearing fighter jets in the sky.

Iranian outlets say that air defences have been activated in the city.

Iran's state TV is reporting that "an American A10 aircraft was shot by the defence systems of the Army Air Defence Force and crashed in the Persian Gulf in southern Iran", citing the Iranian Army.

It adds that it was shot down hours ago around the Strait of Hormuz.

It's not clear if this is the same A-10 Warthog that the BBC's US partner CBS reports was hit during the search and rescue effort for the F-15E.

Two US aircraft involved in the rescue of the American F-15 fighter jet over Iran have also come under fire, according to two US officials speaking to CBS.

The BBC's US partner reports that an A-10 Warthog taking part in the search and rescue was hit, with the pilot ejecting over the Gulf, where he was rescued.

Two helicopters were also involved in the search, rescuing one of the two F-15E airmen from the earlier crash, CBS says, and the helicopter carrying a recovered pilot was hit by small arms fire, injuring crew members on board. The helicopter landed safely and the personnel are being treated.

CBS earlier reported that the F-15 was shot down early afternoon local time, but there have been conflicting reports about the timing.

The search is still reportedly under way for the second crew member, a weapon systems officer.

An Egyptian man has died during an evacuation after falling debris struck gas facilities, according to authorities in Abu Dhabi.

Two fires broke out at the Habshan gas facilities "following a successful interception" by air defence systems, the Abu Dhabi media office says.

An assessment is under way at the site, the office adds.

The death toll from strikes on Thursday on a bridge in Karaj - a city near Tehran in Alborz province - has risen to 13, according to Amirhossein Daneshkohan, Director General of the Alborz Foundation of Martyrs and Veterans Affairs in Iran.

Earlier today, we reported that the death toll was eight.

Daneshkohan said those killed were from “all walks of life”, including “municipal employees”.

Iranian media reported that 95 people were injured when the bridge under construction was bombed.

US President Donald Trump has warned Iran there will be strikes on its bridges and electric power plants if its leaders do not agree to his terms to end the war.

Israel's military has delayed strikes in the area of Iran where the search for missing US fighter jet crew is under way, according to reports from CNN, AP news agency and Israel's Channel 12.

CNN says an Israeli official told the network that strikes had been postponed in the search area, while Channel 12, citing a senior Israeli official, reported the strikes had been cancelled. AP also reported that air strikes had been halted in relevant areas due to the rescue efforts.

AP says the Israeli official spoke to them on condition of anonymity "because the operation is ongoing".

The Israel Defense Forces has not confirmed these reports.

I’ve just spoken to two military analysts, who say what’s most striking about Iran reportedly shooting down a US fighter jet is that it didn’t happen sooner.

“It was sort of inevitable,” says Jennifer Kavanagh, a senior fellow and director of military analysis at think tank Defense Priorities.

It was only “a matter of time before there was some incident like this”, she says.

“We know that Iran has anti-aircraft weapons, and the idea that they had all been eliminated was quite hard to believe and likely inaccurate from the start,” she adds.

US President Donald Trump has repeatedly said that Iran’s air capabilities have been obliterated.

James Jeffrey, a military strategy expert and fellow at think tank The Washington Institute, also says it’s “amazing” that this is the first fighter jet Iran reportedly shot down.

But both Jeffrey and Kavanagh say that, in the grand scheme of the war, this incident matters very little.

While it’s "a big victory" for Iran to have shot down an American jet, for the US, losing a single aircraft “isn’t going to change the operational outcome of the war,” Kavanagh says.

BBC Verify has spoken to an expert who confirms that debris in images widely circulating on social media has come from a US F-15E Strike Eagle.

The piece shown are a wingtip and part of a vertical stabiliser from a plane from the US 494th Fighter Squadron based at RAF Lakenheath in the UK, according to Justin Bronk, senior research fellow for airpower and technology in the Military Sciences team at the Rusi think tank.

A reverse image search shows the images only began to circulate on social media today.

We cannot confirm where the images were taken as they are close-ups and there isn't a clear sign that lets us geolocate them, but we have checked them for AI and there are no signs of manipulation.

While we don’t know exactly where the jet was downed, there are names of two provinces mentioned frequently on Iran’s state media so far - Khuzestan and Kohgiluyeh-Boyerahmad.

BBC Verify has confirmed that a video showing what appears to be a US plane accompanied by two helicopters flying over southern Iran was recorded in Khuzestan province.

Khuzestan is a core centre of Iran’s economy and a major powerhouse for oil and a number of other industries. The province is home to more than 4.7 million people.

Its major steel company was recently targeted during the war and shut down as the result of strikes.

Right next to Khuzestan is mountainous Kohgiluyeh - more than 700,000 are estimated to be living there.

Iranian news outlets have published a video claiming to show people there “searching for the American pilot”.

An Iranian state TV newsreader for a local channel has reported that rewards will be given to anyone who captures the pilot alive.

Information is still coming in after reports that a US fighter jet has been downed over Iranian territory.

What we know:

• An F-15E fighter jet has reportedly been downed over southern Iran
• One crew member from the jet has been rescued by US forces, according to the BBC's US partner CBS - an F-15E jet usually has a two-person crew
• US President Donald Trump has been briefed on the situation, according to White House Press Secretary Karoline Leavitt
• Iranian media report that authorities have offered a reward of 10 billion tomans (about £50,000) for anyone who captures a downed US crew member alive

What we don't yet know:

• While one crew member has reportedly been rescued, there is no word yet on any others
• The circumstances surrounding the downing of the jet are still unclear
• We have not yet heard from Trump or the Pentagon

As reports suggest a search and rescue operation is under way for a downed US F-15 fighter jet in southern Iran, fighting continues.

The Israel Defense Forces (IDF) says it has launched another wave of strikes in Tehran.

In the past 24 hours, it says it has carried out "more than 70 strikes in western and central Iran targeting ballistic missile launch sites and unmanned aerial vehicles".

In a separate update, the IDF says it has started striking parts of Beirut.

It also reports detecting multiple barrages of missiles fired at its territory from Iran throughout the day.

Footage widely shared on social media and Iranian state media showing US warplanes over Iran matches typical search and rescue mission manoeuvres, according to the BBC's US partner CBS.

CBS national security analyst Aaron MacLean says the footage seems to show US aircraft flying at low altitudes in broad daylight over hostile territory.

He says this is something the US would only do if it had a good reason, such as trying to rescue a downed pilot or pilots.

Iranian parliament speaker Mohammad Bagher Ghalibaf has mocked the US on his X account after reports that an American fighter jet was shot down over Iran.

“After defeating Iran 37 times in a row, this brilliant no-strategy war they started has now been downgraded from 'regime change' to 'Hey! Can anyone find our pilots? Please?',” a post on Ghalibaf's account says.

Trump said on 31 March that there has been regime change in Iran, saying the new crop of Iranian leaders are "much less radicalised" and more "rational".

Ghalibaf has also sarcastically posted, "Wow. What incredible progress. Absolute geniuses."

His account has been very active recently, posting occasional memes, while he was last seen on state TV on 17 March.

Some unconfirmed reports suggested the Trump administration was considering Ghalibaf as a potential partner and possibly even a future leader.

We’ve had reports from anonymous officials saying a US F-15 was downed over Iran, but there’s been little public comment from either the White House or the Pentagon.

So far, the only word from the White House is that President Trump has been briefed on the situation.

This is likely because search and rescue efforts were still under way, making public confirmation difficult and sensitive during a delicate operation.

We now know that one crew member has been recovered, according to CBS, the BBC’s US partner.

Officials are expected to face questions about the circumstances of the incident.

US officials, including Trump and Defence Secretary Pete Hegseth, have repeatedly said Iran’s air defence capabilities have been destroyed in the conflict.

A confirmed shoot-down of a fighter jet would immediately raise questions about Iran’s ability and willingness to continue the fight, and the threat it might pose to US personnel and aircraft over the country.
