U.S. President Donald Trump on Thursday threatened to destroy Iran’s bridges and power plants, saying the “New Regime leadership knows what has to be done, and has to be done, FAST!” in a Truth Social post.

Trump did not elaborate on what needed to be “done,” but said the U.S. “hasn’t even started destroying what’s left in Iran.”

Hours later, Iran’s semi-official Tasnim news agency reportedly claimed that a U.S. F-35 fighter jet was shot down over central Iran. Images of the jet were posted on Telegram, with one photo that appeared to show the words “U.S. Air Forces in Europe” on what appeared to be the tail section of a plane.

The U.S. Central Command, which oversees the region, and Iranian authorities did not respond to a request for comment at the time of publication.

Trump’s latest threat came a day after a nationwide address in which he said the U.S. military would hit Iran “extremely hard” for the next two or three weeks. He added that the U.S. would “bring them back to the Stone Ages where they belong.”

Hours after his speech, Iranian Foreign Minister Abbas Araghchi struck a defiant tone on X, saying that “there was no oil or gas being pumped in the Middle East back then,” referring to Trump’s stone age remarks.

“Are POTUS and Americans who put him in office sure that they want to turn back the clock?” Araghchi said.

Iran has effectively shut tanker traffic through the Strait of Hormuz, a vital global oil route, after the U.S. and Israel attacked the country on Feb. 28.

Trump has repeatedly threatened to send Iran back to the “stone age” as the war entered its second month and the U.S. military build-up in the Middle East showed no signs of slowing.

Despite reports of overtures from the U.S., including ceasefires and a 15-point peace plan to end the war, Iran has publicly contradicted multiple reports about negotiations with the Trump administration on numerous occasions.

Tehran had described the 15-point proposal as “extremely maximalist and unreasonable,” according to an Al Jazeera report on March 25, citing a high-ranking diplomatic source.

Trump said Wednesday that Iran’s “New Regime President” had asked Washington for a ceasefire, a claim that Tehran has denied. Trump has not specified who the “President” is.

“We will consider when Hormuz Strait is open, free, and clear. Until then, we are blasting Iran into oblivion or, as they say, back to the Stone Ages!!!,” he wrote.

Attacks on power plants could constitute a war crime and violate international law, legal experts said.

In a letter dated Thursday and signed by over 100 law experts, the group said international law prohibits attacks on “objects indispensable to the survival of civilians, and the attacks threatened by Trump, if implemented, could entail war crimes.”

Trump had also earlier said that he could target water desalination plants in Iran.

The Gulf Cooperation Council on Thursday called on the United Nations Security Council to take “all necessary measures to ensure the immediate cessation of Iranian aggressions against the Council states.”

The six countries in the Gulf Cooperation Council — Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates — have come under attack from Iranian missiles and drones as the war entered its second month.

The Kuwait Petroleum Corporation said that its Mina al-Ahmadi refinery was hit by drones early on Friday.

Jassim Albudaiwi, Secretary-General of the Gulf Cooperation Council, said that while the bloc does not seek war, Iran had “exceeded all red lines” and described Tehran’s attacks as “treacherous.”

Bahrain, the current rotating president of the Security Council, has led an effort to pass a U.N. resolution to ​authorize “all necessary means” to protect commercial shipping in and around the Strait of Hormuz.

But the proposal reportedly stalled after veto-wielding Security Council members China, Russia and France objected to the draft resolution, which would have authorized military action against Iran.

Senate Majority Leader John Thune, R-S.D., and House Speaker Mike Johnson, R-La., on Wednesday backed a two-track plan to fund the Department of Homeland Security, paving the way to fund the Transportation Security Administration in the near-term while punting debate over the agency’s more controversial immigration enforcement functions. 

The announcement amounts to a reversion back to the bill the Senate passed last week that would have funded all of DHS except for Immigration and Customs Enforcement and parts of Customs and Border Protection. Democrats have called for changes to immigration enforcement practices before funding those sub-agencies.

Initial DHS funding for most of the department would be followed by a second measure using a Senate procedure known as budget reconciliation for ICE And CBP, the Republican leaders said Wednesday in a joint statement. Used only for spending-related measures, that process allows the Senate to approve with a simple minority, as opposed to the 60-votes needed to overcome a filibuster.

“In the coming days, Republicans in the Senate and House will be following through on the President’s directive by fully funding the entire Department of Homeland Security on two parallel tracks: through the appropriations process and through the reconciliation process,” Thune and Johnson said in the statement.

Congress is in the first week of a two-week recess and is not due to return until April 13. DHS has been shut down since February, after federal agents killed to U.S. citizens in Minneapolis as part of an immigration crackdown. Democrats have refused to fund the agency until changes to DHS’s immigration enforcement policies are implemented.

Thune and Johnson’s joint statement came after the House GOP revolted on Friday and killed the Senate plan.

Rather than take a vote on the Senate DHS bill that advanced early Friday morning, Johnson announced a plan to pass a stopgap spending measure that would fund all of the agency at its current levels through May 22. That continuing resolution passed 213-203, with three Democrats joining all Republicans in support.

Johnson’s strategy guaranteed the extension of the shutdown that had disrupted air travel across the country, as unpaid TSA agents called out of work and quit in large numbers, ramping up pressure on lawmakers to reach an agreement ahead of heavy travel for the Passover and Easter holidays in early April.

But Congress got some cover from President Donald Trump, who announced last week he would draw from unspent funds from the 2025 Republican tax and spending package, known as the One Big Beautiful Bill Act, to pay TSA agents. Those agents began to receive paychecks, and the lines at airport security appeared to ease this week.

Trump earlier Wednesday appeared to back a two-track approach in a post to Truth Social, calling on Congress to get bill to his desk by June 1 using the budget reconciliation process.

“(W)e are going forward to fund our incredible ICE Agents and Border Patrol through a process that doesn’t need Radical Left Democrat votes, and bypasses the Senate Filibuster (which should be repealed, IMMEDIATELY!), working in close conjunction with House Speaker Mike Johnson and Senate Leader John Thune,” Trump posted. “We are going to work as fast, and as focused, as possible to replenish funding for our Border and ICE Agents, and the Radical Left Democrats won’t be able to stop us.”

The consensus from Republican leaders could signal the end of the partial government shutdown, but budget reconciliation can be a long and arduous process.

Senate Budget Committee Chair Lindsey Graham, R-S.C., has said he has already begun work on reconciliation and would strive to meet the June 1 deadline.

“This bill will focus on ensuring ICE and other vital functions of homeland security, as well as the U.S. military and efforts to increase voter integrity, are Democrat-resistance proof. I will be working closely with @POTUS and his team in writing this bill,” Graham posted to X on March 26.

But Congress will have to do the hard work of deciding which GOP priorities make it into the final package. Lawmakers have floated a grab bag of proposals that extend well beyond funding for ICE and border patrol, including supplemental funds for the Iran war and a Trump-backed voter identification and noncitizen voting bill. If more things get added, it could complicate the chances of the Senate parliamentarian allowing a simple-majority vote to approve a measure.

“In following this two-track approach, the Republican Congress will fully reopen the Department, make sure all federal workers are paid, and specifically fund immigration enforcement and border security for the next three years so that those law-enforcement activities can continue uninhibited,” Thune and Johnson wrote Wednesday.

European defense tech startups are ramping up commercial discussions with Middle East governments since the Iran war, company execs told CNBC. Another CEO said interest from Gulf states was “skyrocketing” as they race to bolster measures to counter drone and missile attacks.

Iran has targeted its neighbors since a joint U.S.-Israeli military operation began at the end of February, with more than 3,000 drones and missiles having been fired on the United Arab Emirates, Saudi Arabia, Bahrain and Kuwait, according to data compiled by think tank the Center for Strategic and International Studies.

European startups that develop defense technology, in particular drone and missile interceptors, told CNBC they were increasingly talking with and receiving approaches from Gulf states to supply their militaries. Others are ramping up hiring in the region as they look to meet the demand for their systems.

Earlier this month, the Financial Times reported that the company was in talks to raise new funding at more than a $1 billion valuation.

UK-based startup Valarian, which builds digital infrastructure for sensitive use cases including those in defense, didn’t have defense contracts with Gulf states before the Iran war but has seen commercial discussions with them increase since the conflict began, CEO Max Buchan told CNBC.

Uforce has seen interest from Gulf states in its defense tech “skyrocket” since the beginning of the Iran war, CEO Oleg Rogynskyy told CNBC. Uforce is developing several defense technologies, including counter-uncrewed aerial systems (UAS), maritime and strike drones and battlefield software.

“We’re having a ton of inbound interest,” he said. “Gulf states are coming to us to figure out how to do large-scale, unmanned operations.” That included intercept, de-mining, strike, future convoy and escort and patrol operations at sea, Rogynskyy added.

Uforce has been providing defence tech for Ukrainian operations in the Black Sea, he told CNBC, adding that the lessons from that war “are directly applicable to what is happening in Iran, both from an operational, tactical and strategic perspective.”

“We are looking at the very similar mine and missile-based sea denial from the Iran side, to how Russia prevented Ukrainian grain from being exported, initially.”

Uforce, which raised $50 million at a valuation above $1 billion earlier this month, is now looking to hire a team permanently based in the Middle East, because of the demand caused by the Iran war. The company currently has a Ukrainian delegation in the region, but aims to recruit five to 10 employees in the next few weeks, Rogynskyy told CNBC.

Frankenburg is also looking to build out a Middle East-based team. The startup didn’t have any employees in the region before the war, but is now looking to hire there “significantly,” CEO Salm told CNBC. While the Middle East has been a focus of Frankenburg since the company’s inception in 2024, hiring plans have been accelerated because of the Iran war, he said.

Defense tech startups in Europe have raised record sums in recent years as global geopolitical tensions have risen. The sector picked up $1.8 billion in 2025, according to deal-counting platform Dealroom, nearly three times the previous highest yearly figure, and has already raised $854 million so far in 2026.

The U.K. and Germany have emerged as key hubs of this wave of new defense companies, with France and Ukraine also developing increasingly well-funded startups.

German arms maker Rheinmetall said it sees this year’s sales growing by as much as 45% as it reported 2025 revenue growing 29% year-over-year, missing expectations.

It also said it was in a “prime position to help the US replenish their missile stockpiles” used in the war in Iran, such as supplying critical solid rocket motors.

In a presentation to accompany earnings on Wednesday, the company said “higher spend for missile restocking and air defence” was “inevitable.”

It comes as defense companies are expected to be on the receiving end of governments’ hiked spending on military capabilities, amid increased demand due to the wars in Ukraine and Iran. Rheinmetall expects its order backlog to more than double to 135 billion euros this year.

“The tense security situation underpins the promising position of the Group, whose products are playing an increasingly important role for the increase in defence capabilities in Germany and its partner countries,” Rheinmetall said.

The defense giant, Germany’s seventh-largest company by market value, issued its 2026 outlook, which it had hinted at during a preclose call in early February.

Group sales are expected to grow by between 40% and 45% to between 14 billion ($16.26 billion) and 14.5 billion euros. Operating result margin is expected to be around 19%, up from 18.5% in 2025. Jefferies analysts called the guidance “realistic but soft.”

“The world is changing rapidly, and Rheinmetall is well prepared,” said CEO Armin Papperger in a statement.

“With our products, we will have a significant share in the increasing equipment spend of the armed forces and deliver what modern armed forces need in the 21st century.”

Shares fell 5.2% in early trading on Wednesday while the pan-European Stoxx 600 index was down 0.7%.

Sales grew by 29% over the full year to 9.94 billion euros ($11.56 billion), missing expectations of 10.53 billion euros, according LSEG estimates.

Earnings before tax and interest came in at 1.68 billion euros, compared with estimates of 1.75 billion euros, while the order backlog reached a record high of 63.8 billion euros, a 36% jump from the previous year. 

“As budget approvals resumed toward year‑end and defence spending picked up across Europe – particularly in Germany – we expect delayed programmes to convert into contracts, supporting a rebound in nominations and reinforcing the company’s already elevated backlog,” noted Morningstar analyst Loredana Muharremi ahead of the print. 

In February, the company indicated sales for this year would come in at between 13.2 billion and 14.1 billion euros, and EBIT between 2.4 billion and 2.8 billion euros, both more than 10% below expectations. Shares subsequently fell 6.5%.

Barclays analysts in February called the share move following the indicated guidance “a marked over-reaction,” saying that “expectations are high, and shares continue to be very sensitive to any information that comes out.”

Noting some confusion over the like-for-like numbers this year, given recent changes to the business structure, the analysts said that weapon and ammunition growth will remain elevated, and there is scope for its naval business to be resilient, too. 

“From a structural perspective we think nothing has really changed here: the backlog growth in 2026 will be material.”

Rheinmetall shares have risen about 540% over the past three years, as a leading provider of land systems and ammunition in Europe.

Gains, however, have moderated over the past year as some investors question whether shares have reached their full value and if growth can be sustained long-term. Coming into Wednesday trading, the stock was up just 3.4% year-to-date. 

Rheinmetall and other defense firms like Britain’s Bae Systems and Italy’s Leonardo are viewed as well-placed to capitalize on hiked spending by European governments over the next five years against a backdrop of the Russia-Ukraine war.

Rheinmetall is looking to sell its civilian automotive to focus purely on meeting demand for its defence business. It’s also now active in the naval sector following its acquisition of shipbuilder Naval Vessels Lürssen, which closed in February.

Shares of defense companies, including Rheinmetall, initially spiked after the U.S. and Israel launched attacks on Iran on Feb. 28, killing its Supreme Leader, Ayatollah Ali Khamenei. It raised fears that the attacks would develop into a full-blown war engulfing the entire Middle East region, which would eventually lead to more demand for military equipment.

Senate Democrats on Tuesday rebutted President Donald Trump’s claims that the war in Iran may soon be over, warning that the U.S. risks getting dragged into another prolonged conflict in the Middle East.

The concerns from Democrats who attended a bipartisan classified briefing with military brass on Tuesday stand in stark contrast with the president, who on Monday suggested the U.S. may be nearing the completion of its operation. Trump’s statements sent slumping markets soaring and cratered oil prices that had skyrocketed in recent days.

The senators were briefed as the Trump administration continues to whipsaw between explanations, goals and timelines for the war that has seen eight U.S. service members killed in action and left the longtime leader of Iran, Ayatollah Ali Khamenei, dead.

“What I heard is not just concerning, it is disturbing,” Sen. Jacky Rosen, D-Nev., a member of the Senate Armed Services Committee, whose members were briefed. “I’m not sure what the endgame is or what their plans are. … And if he does want to put us in a forever war, which it seems like he does, he needs to come out and let us be able to have that discussion.

“Do you think because he thinks he waves some magic wand that everything just stops? … It’s not going to stop just because he wishes it to be so,” Rosen said.

The pessimism from Democrats on an eventual U.S. end for the war it started with Israel against Iran comes as Congress awaits a potential supplemental funding request to finance the offensive. The effort has burned through billions of dollars of U.S. munitions, which will have to be refilled. Some Democrats said they would resist any request for further funding. Democrats have also balked at Trump failing to seek congressional authorization to begin the war.

“At this point, I am a hard no on a supplemental,” said Sen. Elizabeth Warren, D-Mass., the top Democrat on the Senate Banking Committee. “No more money. The one thing Congress has the power to do is to stop actions like this through the power of the purse.”

“This is not a war supported by this country, and this is not a war that makes us safer,” Warren said.

Lawmakers exiting the meeting said the size of the potential supplemental package was not given. Republicans, who hold a 53-47 vote majority in the Senate, appeared willing to support more funding for the war when they left the briefing.

“Not in total dollar amounts that I’ve heard,” said Sen. Jim Banks, R-Ind. “Obviously, there’s a cost to it, but the trade-off is exponentially more, and this has been a very effective operation so far.”

“We need to do whatever it takes to accomplish the mission and do it as fast as we can,” Banks said.

The Washington Post on Monday reported that the military burned through $5.6 billion in munitions in the first two days of the war that began Feb. 28. Washington-based bipartisan think tank the Center for Strategic and International Studies estimates that the war is costing roughly $891 million per day.

Sen. Tim Sheehy, R-Mont., a former Navy Seal, suggested the cost is worth it.

“Iran’s been at war with us for 47 years; we’re trying to end this war,” Sheehy said, referencing the years since the Iranian regime came to power. “We’ve had two presidential administrations give billions of dollars to Iran, that’s what really cost [money].”

Trump and Defense Secretary Pete Hegseth have painted a different picture of the timeline of the war than Democrats say they fear. Hegseth, at a press briefing earlier Tuesday pledged the U.S. will not enter another prolonged conflict in the Middle East, and Trump on Monday said the war would end “very soon.”

War costs are expected to only grow as the war drags on, and Democrats are warning there is no end in sight. The war dragging on could also see markets whip back and oil costs continue to soar, especially as the Strait of Hormuz, which carries roughly 20% of the world’s oil remains largely impassible.

Sen. Tim Kaine, D-Va., said there was “no discussion” about the safety of passing through the Strait during the briefing while he was in attendance.

Sen. Mark Kelly, D-Ariz., a retired Navy captain, also said the U.S. doesn’t appear to be nearing the end of the war after leaving the meeting.

“Clearly, they do not have a strategic goal,” he said. “They didn’t have a plan, they have no timeline. Because of that, they have no exit strategy.”

Correction: This story has been revised to reflect that Sen. Tim Sheehy, R-Mont., is a former Navy SEAL. A previous version misidentified the branch of the military in which he served.

It was no surprise, when equity markets first reacted to news of the strikes on Iran, that the U.K.’s FTSE 100 fell by less than all of its major continental European peers.

Accordingly, when QatarEnergy suspended LNG production at the Ras Laffan and Mesaieed industrial cities on Monday, U.K. natural gas futures rose by more than 40%.

UK PM Keir Starmer suffers major blow after his party comes third in key vote. The result in Gorton and Denton, in Greater Manchester, is likely to intensify speculation about Starmer’s position,

Global defense stocks jumped on Monday as investors reacted to a dramatic military escalation in the Middle East over the weekend.

The sector was a rare bright spot amid a broader market sell-off triggered by fears of a wider regional conflict.

Germany’s Hensoldt and Britain’s BAE Systems were among the top performers in the Stoxx 600, both up around 4%. Defense names Thales, Renk, and Leonardo rose between 4% and 1%, paring earlier gains, while the broader Stoxx 600 index fell more than 1%, touching a two-week low.

Stateside, U.S. firms Lockheed Martin and Northrop Grumman each rose more than 5% in premarket trading. Futures tracking the S&P 500 were down 1.1%.

With South Korean markets closed Monday, regional activity in Asia-Pacific defense sector was somewhat muted. Japan’s defense heavyweights Mitsubishi Heavy Industries and IHI rose about 3% each, while Singapore’s ST Engineering climbed 2.8%.

The moves come after the U.S. and Israel launched widespread attacks on Iran over the weekend that killed Iranian Supreme Leader Ayatollah Ali Khamenei, ending his 36-year rule. Retaliatory strikes by Iran against U.S. bases in the Middle East killed three U.S. service members.

Prospects of an escalation also led oil prices and energy companies’ shares to surge.

“It’s very much one of uncertainty at the moment that investors are grappling with,” said Patrick O’Donnell, Chief Investment Strategist at Omnis Investments.

“Equity markets are a little bit more uncertain about just how long this is going to drag on, for the implication for both growth and inflation that it will have the longer that it goes on,” O’Donnell told CNBC’s “Squawk Box Europe” on Monday.

“Really, it’s a question of… what’s the duration of this conflict?”

The conflict with Iran entered a third day on Monday, with U.S. President Donald Trump warning of further American casualties and saying the conflict could last for up to four weeks. 

In June last year, the U.S. and Israel launched air strikes that damaged three Iranian nuclear sites.

Carl Bildt, former Prime Minister of Sweden and co-chair of ECFR’s Council, said it was expected that Iran would strike back at the American military facilities in the Gulf region, “but now it seems like they are striking other targets across the Gulf as well.”

“That is surprising, but also highly disturbing, because, of course, the stability of the Gulf countries is important to us all, important to the global economy, important to the region,” he said.

President Donald Trump on Friday said that “I’d love not to use” the U.S. military to attack Iran, “but sometimes you have to.”

But Trump also said, “We haven’t made a final decision” on whether to attack Iran.

“We’ll see what happens,” he said. “We’re talking later today. We’ll have some additional talks today.”

Trump’s comment to reporters outside the White House came after he expressed frustration at Iran’s refusal to comply with American demands to curb its nuclear program.

“We’re not thrilled with the way they’re negotiating,” Trump said. “They cannot have nuclear weapons.”

“I’m not happy that they’re not willing to give us what we have to have,” Trump said, referring to that condition.

Asked by a reporter if there could be a long, drawn-out conflict in the Middle East if the United States attacks Iran, Trump said, “I guess you could say there’s always a risk.”

“It’d be wonderful if they negotiate, really, in good conscience, good faith,” he said. “They are not getting there so far.”

Omani Foreign Minister Badr al-Busaidi, who has been mediating negotiations between the U.S. and Iran, met in Washington, D.C., with Vice President JD Vance and other American officials in a bid to avoid war.

A statement issued by Oman’s government after the meeting put a positive spin on those talks that was not reflected in Trump’s blunt comments.

“The meeting examined the indirect US-Iran negotiations sponsored by the Sultanate of Oman, alongside the diplomatic endeavours seeking to culminate in a just and enduring agreement concerning the nuclear file and to guarantee the peaceful character of Iran’s nuclear energy program,” Oman’s government said.

“I am grateful for their engagement and look forward to further and decisive progress in the coming days,” al-Busaidi said in a post on X. “Peace is within our reach.”

During an interview with MS Now, when asked if there was a chance of the United States attacking Iran overnight, al-Busaidi said, “I can’t answer that question, because I don’t know.”

“I think President Trump is sincerely passionate for a deal,” al-Busaidi said. “He wants to have a deal. He wants to have a diplomatic solution, and this is what we are trying to do.”

But Trump, in a speech later Friday afternoon in Corpus Christi, Texas, said of Iran, “We have a very big decision.”

“We have a country that’s been 47 years blowing people’s legs off, arms off,” Trump said. They’ve been knocking out ships, killing people, lots of people, not only Americans, lots of people.”

Trump said he wanted to “make a deal that’s meaningful.”

“I’d rather do it the peaceful way,” Trump said, while calling Iran’s government “very difficult people, dangerous people, very difficult people.”

The U.S. Embassy in Jerusalem earlier Friday authorized non-emergency U.S. government personnel and their family members to leave Israel “due to safety risks.”

Also Friday, the massive American aircraft carrier, the USS Gerald Ford, arrived off Israel’s coast.

Also on Friday, the State Department said that Secretary of State Marco Rubio would visit Israel on Monday and Tuesday to discuss Iran and other regional issues.

European defense companies must take a stronger lead on collaborating to help the continent become independent of the U.S. security umbrella, Leonardo‘s CEO told CNBC.

Speaking with CNBC’s “Squawk Box Europe” on Wednesday after Leonardo’s annual results statement, Roberto Cingolani said European defense companies have “all the capabilities and technical skills” and should not wait for governments to fix the sector, which he warned was “fragmented.”

Companies should take the lead in a process of “aggregation”, which European governments would follow, he said, adding that this approach “pays a lot” and helps enable companies to become “better, faster, more profitable.”

He pointed to Leonardo’s partnership with the U.K.’s BAE Systems and Japan’s Mitsubishi Heavy Industries as co-founders of the Global Combat Air Programme (GCAP) to jointly develop the Tempest stealth fighter.  

Leonardo has also developed joint agreements with German defense giant Rheinmetall for land defense systems, and with Turkish drone maker Baykar, he said.

Last October, Leonardo also unveiled plans for a combined space and satellite company with Airbus and Thales to rival Elon Musk’s Starlink.

“I’m firmly convinced nobody can make it on their own,” Cingolani told CNBC. “We need to deploy synergies, we need to understand joining forces in a competitive industry like defense is fundamental to be successful, to be fast in responding to the needs of our societies.”

U.S. President Donald Trump’s bid to annex Greenland contributed to fractures in the NATO alliance, as the war in Ukraine focuses attention on Europe’s defense.

His comments came after Leonardo reported an 18% annual increase in core profits — topping 1.75 billion euros ($2.1 billion) — in its latest earnings statement on Wednesday.

New orders rose 14.5% last year, to 23.8 billion euros, powered by its aeronautics division, as net debt sat at 1 billion euros — a 44% decrease for the Rome-headquartered, Milan-listed company.

Its shares finished Wednesday’s session 3.5% down after the earnings.
