Israel-Iran conflict

UK Prime Minister Keir Starmer has allowed the US to use British bases for so-called “defensive strikes” targeting Iran, after Tehran started hitting civilian targets. Still, Al Jazeera’s Milena Veselinovic explains why US President Trump says the US-UK relationship isn’t what it used to be.

US and Israeli strikes against Iran, which have sparked a regional war, likely violate the UN Charter’s prohibition on aggression and lack any valid legal justification, experts say.

“This is not lawful self-defence against an armed attack by Iran, and the UN Security Council has not authorised it,” the United Nations special rapporteur on the promotion of human rights and “counterterrorism”, Ben Saul, told Al Jazeera.

“Preventive disarmament, counterterrorism and regime change constitute the international crime of aggression. All responsible governments should condemn this lawlessness from two countries who excel in shredding the international legal order.”

The administration of United States President Donald Trump did not seek authorisation from the UN Security Council – or even from domestic lawmakers in Congress – for the war.

And Iran did not attack the US or Israel prior to the strikes that killed Iranian Supreme Leader Ali Khamenei and several other senior officials, as well as hundreds of civilians.

Yusra Suedi, assistant professor in International law at the University of Manchester, said there are grounds to believe that the attacks against Iran amount to a crime of aggression.

“This was an act of use of force that was unjustified,” Suedi told Al Jazeera.

International law is a set of treaties, conventions and universally accepted rules that govern relations between countries.

Imminent threat?

The Trump administration has argued that Iran posed a threat to the US with its missile programme and nuclear programme, arguing that military action was necessary.

But the UN Charter prohibits unprovoked attacks against other countries.

“All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations,” the founding document of the UN says.

Rebecca Ingber, a professor at Cardozo School of Law at Yeshiva University who previously served as an adviser to the US Department of State, said that the prohibition of the use of force is a “bedrock” principle of international law that allows for only limited exceptions.

“States may not use force against the territorial integrity of other states except in two narrow circumstances — when authorised by the UN Security Council or in self-defence against an armed attack,” said Ingber.

Suedi said one instance in which the use of force can be legal is when a country seeks to thwart an imminent attack by another state.

Trump has said that the goal of the war is to “defend the American people by eliminating imminent threats from the Iranian regime”.

But Suedi cast doubt over that assertion.

“Imminence in international law is really understood to be something that is instant, something that is overwhelming, something that leaves really no other choice but to act first, something that is pretty much happening now,” Suedi said.

She noted that Trump himself had said repeatedly that the June 2025 US attacks on Iran “obliterated” the country’s nuclear programme, and that Tehran and Washington were holding talks when the war broke out on Saturday.

“There really was no evidence of an imminent threat, and that the attack was a pre-emptive strike,” Suedi told Al Jazeera.

“If it’s pre-emptive, it means that you are acting to counter something that is in the future, hypothetical, speculative, and that is not imminent, but that’s exactly what happened here. That is illegal under international law.”

US officials, including Trump, have said that Iran was building a ballistic missile arsenal to protect its nuclear programme and later build a nuclear bomb.

‘Scattershot’ arguments

Trump has also said that he is seeking “freedom” for the Iranian people, as the US president’s aides have described the regime in Tehran as brutal.

In January, Iran responded to a wave of anti-government protests with a heavy security crackdown. The violence killed thousands of people.

Trump encouraged the demonstrators to take over government buildings at that time, promising them that “help is on the way”.

Experts say a humanitarian intervention to help protesters in Iran would have required UN Security Council authorisation to cross the legal threshold.

“The rationales have been scattershot,” Brian Finucane, a senior adviser for the US programme at the International Crisis Group, said of the US justifications for the strikes.

“Certainly none of them amount to a serious international legal argument.”

Beyond the possible breaches of the UN Charter, the US-Israeli attacks risk violating provisions of international humanitarian law that are meant to shield civilians from war.

An Israeli or US attack on a girls’ school in the southern Iranian city of Minab on Saturday killed at least 165 people, local officials have said.

“Civilians are already paying the price for this military escalation,” Annie Shiel, US Director at Center for Civilians in Conflict (CIVIC), told Al Jazeera in an email.

“We are seeing deeply alarming reports of attacks on schools and critical civilian infrastructure in Iran and across the region, with devastating casualties, including many children. These strikes risk igniting a wider regional catastrophe.”

Embrace of military power

The strikes on Iran are the latest instance yet of Trump’s reliance on the brute force of the US military power to promote his global agenda.

During Trump’s second term, the US has threatened to use military force to seize the Danish territory of Greenland, killed at least 150 people in a campaign targeting alleged drug trafficking vessels in Latin America, and abducted Venezuelan President Nicolas Maduro in a military attack that killed at least 80 people.

The legality of all of these policies has been questioned domestically and internationally, with UN experts saying that the boat strikes amount to extrajudicial killings.

Trump told The New York Times in January that he is driven by his own morality.

“I don’t need international law. I’m not looking to hurt people,” the US president said at that time.

In recent years, both Democratic and Republican US administrations have also continued to send Israel billions of dollars of weapons despite the Israeli military’s genocidal war on Gaza, which has been documented by rights groups and UN experts.

Ingber, the law professor, said that the use of wanton military force has contributed to a sense of impunity for powerful states and has degraded the international law system that has sought to place some constraints on conflict since the end of World War II.

“The prohibition on the use of force is a relatively recent innovation in the span of things. This rule is policed through the actions and reactions of states, and it feels fragile right now,” she said. “Do we want to go back to a world where states could use force as a tool of policy?”

Iran itself has lashed out against countries across the region in response to the US strikes, launching missiles and drones at military bases as well as civilian targets – including airports, hotels and energy installations.

“In the context of war, from the moment that the first strike was launched, the rules of warfare apply, and they’re very clear that civilian objects and spaces cannot be targeted,” Suedi said.

She said Iran also appears to have violated international law with its response.

Suedi told Al Jazeera that Russia’s invasion of Ukraine and Israel’s brutal assault on Gaza have been showing the “unravelling fragility” of international law.

The war on Iran “is a next episode in that very worrying trend”, she said.

“We’re going to cut off all trade with Spain.” Donald Trump targeted Spain in an Oval Office tirade, complaining about Madrid’s refusal to let its bases be used for attacks on Iran. He also joined the German chancellor in saying Spain doesn’t spend enough on its military.

Iran’s Foreign Ministry spokesman has warned European countries against joining the ongoing war with Israel and the US. His statement comes after France, Germany and Britain said they can take “defensive action” to counter Iran’s missile-launching capabilities.

Despite promising to end United States involvement in costly and destructive foreign wars, President Donald Trump, together with Israel, has launched a massive military assault on Iran, targeting its leadership and nuclear and missile infrastructure.

Much like his predecessors, Trump has relied on military force to pursue US strategic interests, continuing a pattern that has defined US foreign policy for more than two decades.

Since the September 11, 2001, attacks on New York and the US capital, the US has engaged in three full-scale wars and bombed at least 10 countries in operations ranging from drone strikes to invasions, often multiple times within a single year.

The graphic below shows all the countries the US has bombed since 2001.

These may not include all military strikes, particularly covert or special operations.

The cost of decades of war

In the aftermath of the September 11, 2001, attacks, President George W Bush launched what he called a “war on terror”, a global military campaign that reshaped US foreign policy and triggered wars, invasions and air strikes across numerous countries.

According to an analysis by Brown University’s Watson Institute of International & Public Affairs, US-led wars since 2001 have directly caused the deaths of about 940,000 people across Afghanistan, Pakistan, Iraq, Syria, Yemen and other conflict zones.

This does not include indirect deaths, namely those caused by loss of access to food, healthcare or war-related diseases.

The US has spent an estimated $5.8 trillion funding its more than two decades of conflict.

This includes $2.1 trillion spent by the Department of Defense (DOD), $1.1 trillion by Homeland Security, $884bn to increase the DOD base budget, $465bn on veterans’ medical care and an additional $1 trillion in interest payments on loans taken out to fund the wars.

In addition to the $5.8 trillion already spent, the US is expected to have to lay out at least another $2.2 trillion for veterans’ care over the next 30 years.

This would bring the total estimated cost of US wars since 2001 to $8 trillion.

Afghanistan war (2001-2021)

The first and most direct response to 9/11 was the invasion of Afghanistan to dismantle al-Qaeda and remove the Taliban from power.

On October 7, 2001, the US launched Operation Enduring Freedom.

The initial invasion succeeded in toppling the Taliban regime within just a few weeks. However, armed resistance groups mounted a prolonged resistance against US and coalition forces.

The war went on to become the longest conflict in US history, spanning four presidencies and lasting 20 years until the final withdrawal in 2021, after which the Taliban regained control of Afghanistan.

An estimated 241,000 people died as a direct result of the war, according to an analysis from Brown University’s Costs of War project. Hundreds of thousands more people, mostly civilians, died due to hunger, disease and injuries caused by the war.

At least 3,586 soldiers from the US and its NATO allies were killed in the war, which is estimated to have cost $2.26 trillion for the US, according to the Cost of War project.

Iraq war (2003-2011)

On March 20, 2003, Bush launched a second war, this time in Iraq, claiming that President Saddam Hussein possessed weapons of mass destruction – a claim that proved to be false.

On May 1, 2003, Bush declared “mission accomplished” and the end of major combat operations in Iraq.

However, the subsequent years were defined by violence from armed groups and a power vacuum that fuelled the rise of ISIL (ISIS).

In 2008, Bush agreed to withdraw US combat troops, a process completed in 2011 under President Barack Obama.

The drone wars: Pakistan, Somalia and Yemen

Although not declared wars, the US has also expanded its air and drone campaigns.

Beginning in the mid-2000s, the CIA launched drone strikes inside Pakistan’s tribal areas along the Afghan border, targeting al-Qaeda and Taliban figures believed to be operating there. These strikes marked the early expansion of remote warfare.

Obama dramatically expanded the drone strikes in Pakistan, particularly in the early years of his presidency.

At the same time, the US conducted air strikes in Somalia against suspected al-Qaeda affiliates, later targeting fighters linked to al-Shabab as that armed group grew in strength.

In Yemen, US forces carried out missile and drone strikes against al-Qaeda leaders.

Libya intervention

In 2011 during an uprising against Libyan leader Muammar Gaddafi, the US joined a NATO-led intervention in Libya. American forces launched air and missile strikes to enforce a no-fly zone.

Gaddafi was overthrown and killed, and Libya descended into prolonged instability and factional fighting.

Iraq and Syria

From 2014 onwards, the US intervened in the Syrian war with the stated goal of defeating ISIL. Building on its campaign in Iraq, the US conducted sustained air strikes in Syria while supporting local partner forces on the ground.

In Iraq, US forces advised Iraqi troops, fought ISIL remnants and tried to counter Iranian influence, highlighted by a Trump-ordered 2020 strike that killed Iranian General Qassem Soleimani.

Al Jazeera’s Zeina Khodr reports from the site of an Israeli attack in Beirut’s southern suburbs, which Israel says targeted a ‘Hezbollah area’. Israeli forces have taken more land inside Lebanon, expanding a de facto buffer zone that has already displaced tens of thousands of people.

Jeffrey Feltman, former US Assistant Secretary of State for Near Eastern Affairs, questions the legal basis and endgame of the US-Israel war on Iran, saying he does not believe Iran posed an imminent threat to the United States that would justify war.

Iran has held a mass funeral for 165 schoolgirls and staff killed in what it has described as a United States-Israeli attack on a girls school in the southern city of Minab.

Saturday’s strike came on the first day of the joint US and Israeli attacks on Iran. It was the deadliest incident in the campaign against Tehran so far.

The Israeli military said it was not aware of any Israeli or US attacks in that area. Throughout its genocidal war on Gaza, however, Israel has repeatedly denied responsibility for deadly attacks on Palestinian civilians, only to later backtrack when evidence emerged, often describing such incidents as “accidental”.

The attack in Minab has been condemned by UNESCO and Nobel Peace Prize-winning education activist Malala Yousafzai.

Deliberately attacking an educational institution, hospital or any other civilian structure is a war crime under international humanitarian law.

On Monday, Iranian Ministry of Foreign Affairs spokesman Esmaeil Baghaei said the two countries “continue to indiscriminately strike residential areas, sparing neither hospitals, schools, Red Crescent facilities, nor cultural monuments”.

The US-Israeli military campaign that began on Saturday has already killed Iran’s Supreme Leader Ali Khamenei and senior commanders, triggered retaliatory strikes across the region and raised the spectre of prolonged disruption to global energy flows.

While diplomats scramble and the UN calls for restraint, certain defence contractors and energy majors have emerged as early market victors.

As the conflict enters its fourth day, demand for advanced weaponry, missile-defence systems and intelligence platforms is projected to surge.

Lockheed Martin’s stock, the world’s largest defence contractor by revenue, hit a new all-time high on Monday, closing at $676.70 after rising over 4%.

Its F-35 fighters, precision munitions and radar systems are central to the air campaign under way over Iran.

The rally extended across the defence sector.

Northrop Grumman shares jumped 6%, lifted by its stealth-bomber and missile-defence technologies.

RTX, formerly Raytheon, gained nearly 5% while L3Harris Technologies and General Dynamics also recorded solid increases.

Palantir Technologies, whose data-analytics tools support intelligence operations, rose almost 6%.

European companies followed the upward trend on a more modest scale. Germany’s Renk and Italy’s Leonardo posted gains as investors eyed possible increases in NATO procurement and export orders.

Analysts note that defence budgets, already earmarked for growth in 2026, now face even fewer hurdles in Washington and European capitals.

With President Trump stating that operations could last “four to five weeks” or “far longer”, and Iran continuing missile and drone barrages, markets are positioning for weeks of high-intensity military activity.

The gains reflect classic geopolitical risk pricing.

Other market outliers

These rises stand in sharp contrast to broader equity weakness, highlighting how narrowly the benefits are concentrated. Beyond the pure-play defence names, energy companies have been the other clear outperformers, riding the oil and gas wave.

Iranian retaliation has already included strikes to energy sites in Saudi Arabia and Qatar, threats to close the Strait of Hormuz, which could choke off roughly 20% of global oil supply and send energy prices soaring.

The international benchmarks for oil, Brent crude (BZ) and West Texas Intermediate (WTI), are trading at over $82.50 and $75.50 respectively, at the time of writing.

Alongside them, integrated oil majors moved swiftly higher.

ExxonMobil shares rose more than 4% recording a new all-time high, while Chevron, Occidental Petroleum and ConocoPhillips posted comparable gains.

In Europe, Shell and TotalEnergies advanced in line with the global pricing surge.

The QatarEnergy LNG production halt announced on Monday, following Iranian drone strikes on Ras Laffan and Mesaieed facilities, sent European benchmark TTF gas prices over 50% higher, reaching €62/MWh by Tuesday.

Markets reacted swiftly as the indefinite shutdown raised immediate fears of rerouted demand and renewed energy inflation risks in Europe.

LNG equities climbed notably since Monday’s open on the news.

Cheniere Energy, the largest LNG exporter in the US, Venture Global and Australia’s Woodside Energy, all saw intraday strength at the start of the week.

However, analysts caution that actual substitution will take time due to shipping and contract constraints, keeping price action geopolitically sensitive.

The European Commission announced it is closely tracking both price and supply developments and will convene an Energy Task Force with Member States, in liaison with the International Energy Agency, for a meeting sometime this week.

Explosions have rung out across Tehran as the war entered its fourth day with the United States and Israel continuing to pound Iran’s capital and numerous other cities and locations after the assassination of Supreme Leader Ali Khamenei.

Iran continued on Tuesday to retaliate against Israel and throughout the Gulf where nations host US assets.

At least 787 people have been killed in US-Israeli strikes on a minimum of 131 cities across Iran, the Iranian Red Crescent Society said on Tuesday.

Israel’s military said it had “struck and dismantled” the headquarters of Iran’s state radio and television broadcaster, the Islamic Republic of Iran Broadcasting (IRIB), accusing it of “calling for the destruction of the State of Israel and for the use of nuclear weapons”.

In a post on Telegram, IRIB reported explosions near its headquarters in Tehran but said there had been no disruption to its operations.

Tehran’s streets have been largely deserted as people take shelter during the air strikes.

Iranian media also reported explosions in the city of Karaj, just outside Tehran, as well as in the central city of Isfahan.

Iran held a mass funeral on Tuesday for 165 schoolgirls and staff killed on Saturday in what Iran said was a US-Israeli attack on a school in the southern city of Minab.

Israeli attacks on Lebanon have killed more than 50 people. It says the strikes are a response to Hezbollah rockets and drones fired into Israel to protest the US-Israeli killing of Iran’s Supreme Leader.

An unexploded US kamikaze drone was found on farmland in Western Iraq on Monday. The low-cost drones have reportedly been used in US-Israeli strikes on Iran.

‘What is needed now in the region more than anything, is a way out.’ The UN Secretary-General is urging a cessation of hostilities and de-escalation amidst the ongoing US and Israeli military offensive against Iran.

US First Lady Melania Trump has presided over a UN Security Council meeting focusing on children in conflict days after dozens of children at a school in Iran were reportedly killed after Israel and the United States launched attacks.

Iran strikes energy infrastructure across the Gulf as IRGC announces closure of Strait of Hormuz.

Heavy Israeli air strikes have hit multiple parts of Tehran including near the building of Iran’s state broadcaster and the central prison complex. Explosions have been heard across the city.

Ebrahim Jabari, a senior adviser to the IRGC’s commander-in-chief, reiterates that the Strait of Hormuz is ‘closed’.

A commander in Iran’s Revolutionary Guard Corps (IRGC) has said the Strait of Hormuz is closed and warned that any vessel attempting to pass through will be attacked, according to Iranian state media.

“The strait is closed. If anyone tries to pass, the heroes of the Revolutionary Guard and the regular navy will set those ships ablaze,” Ebrahim Jabari, a senior adviser to the IRGC’s commander-in-chief, said on Monday.

Tehran has targeted infrastructure critical to the world’s energy production as part of its retaliation for the Israeli and US bombing campaign that began on Saturday and killed Iranian Supreme Leader Ayatollah Ali Khamenei and other senior officials.

“We will also attack oil pipelines and will not allow a single drop of oil to leave the region. Oil price will reach $200 in the coming days,” Jabbari said in a post on the IRGC’s Telegram channel.

“The Americans, with debts of thousands of billions of dollars, are dependent on the region’s oil, but they should know that not even a drop of oil will reach them,” he was also quoted as saying by the semi-official Tasnim news agency.

Rising energy prices

The Strait of Hormuz, which lies between Iran and Oman, is one of the world’s most critical oil transit routes, with roughly 20 percent of global oil supplies passing through it.

Any disruptions there will further send crude prices soaring and raise fears of a regional escalation.

Energy prices already rose sharply earlier on Monday as disruptions to tanker traffic through the strait, and damage to production facilities, raised uncertainty about how the US-Israeli attacks on Iran would affect supply to the world economy.

The biggest shock was to natural gas prices, which rose by almost 50 percent in Europe and nearly 40 percent in Asia as QatarEnergy, a major supplier, halted the production of liquefied natural gas after its LNG facilities were attacked.

Earlier, Saudi Arabia’s Ras Tanura oil refinery also came under attack from drones, and its defences downed the incoming aircraft, a military spokesman told the state-run Saudi Press Agency. The refinery has a capacity of more than half a million barrels of crude oil a day.

In response, the US said it would take action ⁠to mitigate rising energy prices due to the war with Iran, according to US Secretary of State Marco Rubio.

“Starting tomorrow, you will see us rolling out those phases to ⁠try to mitigate against ⁠that… We anticipated this could be an issue,” Rubio said.

Secretary of state says he hopes Iranian people would overthrow regime as US military says six service members killed.

US Secretary of State Marco Rubio has suggested that a planned Israeli attack against Iran determined the timing of Washington’s assault against the government in Tehran.

The United States’ top diplomat told reporters on Monday that Washington was aware that Israel was going to attack Iran, and that Tehran would retaliate against US interests in the region, so American forces struck pre-emptively.

“We knew that there was going to be an Israeli action. We knew that that would precipitate an attack against American forces, and we knew that if we didn’t pre-emptively go after them before they launched those attacks, we would suffer higher casualties,” Rubio said.

The US secretary of state’s comments came minutes before the US military confirmed that its death toll from the conflict has risen to six after recovering two bodies from a regional facility struck by Iran.

Tehran retaliated against the joint US-Israeli attacks that killed Supreme Leader Ali Khamenei, several top officials and hundreds of civilians with drone and missile launches across the region, including against American bases and assets in the Gulf.

Rubio’s assertion highlights the Israeli role in bringing about the war, which Israeli Prime Minister Benjamin Netanyahu has been seeking for years.

On Sunday, Netanyahu said the attacks on Iran are happening with the assistance of his “friend”, US President Donald Trump.

“This coalition of forces allows us to do what I have yearned to do for 40 years,” the Israeli prime minister said in a video message.

For his part, Rubio told reporters on Monday that an attack on Iran had to happen because Tehran was amassing missiles and drones that it would have used to protect its nuclear programme and acquire an atomic bomb.

Israel and the US launched the war less than 48 hours after a round of talks between American and Iranian officials over Tehran’s nuclear programme.

Rubio said the goal of the war is to destroy Iran’s missile and drone programmes, but stressed the US would welcome ending the current ruling system in Tehran.

“We would not be heartbroken, and we hope that the Iranian people can overthrow this government and establish a new future for that country. We would love for that to be possible,” he said.

Early on Monday, a suspected Iranian drone crashed into the runway at the United Kingdom’s RAF Akrotiri base in southern Cyprus. British and Cypriot officials said the damage was limited. There were no casualties.

Hours later, two drones headed for the base were “dealt with in a timely manner”, according to the Cypriot government.

The incidents came as Prime Minister Keir Starmer signalled on Sunday that the UK was prepared to support the United States in its confrontation with Iran – raising the prospect that it could be drawn deeper into a war it did not choose by its closest ally.

In a joint statement with the leaders of France and Germany, Starmer said the European group was ready to take “proportionate defensive action” to destroy threats “at their source”.

Later, in a televised address, he confirmed that Westminster approved a US request to use British bases for the “defensive purpose” of destroying Iranian missiles “at source in their storage depots, or the launches which are used to fire the missiles”.

But his agreement did little to placate US President Donald Trump, who said the decision came too late.

UK-based military analyst Sean Bell cautioned against reading too much into the Akrotiri incident.

“I understand the projectile that hit Cyprus was not armed, it hit a hangar [with] no casualties, and appears to have been fired from Lebanon,” he said, citing sources.

Al Jazeera was not able to independently verify the claim.

The broader context, he argued, is more consequential.

The US has taken the action “and everybody else is having to deal with the fallout”, he said.

Iran’s military strength lies in its extensive ballistic missile programme, he said, adding that while some have the range to threaten the UK, they do not extend far enough to strike the US.

“I don’t think [US] President Trump has yet made the legal case for attacking Iran, and … international law makes no discrimination between a nation carrying out the act of war and a nation supporting that act of war, so you’re both equally complicit,” he said.

Bell said that Washington likely reframed the issue, communicating to London that, whatever triggered the escalation, US forces were now effectively defending British personnel in the region.

That shift, he suggested, provided a legal basis to “not to attack Iran, but to protect our people”, allowing the UK to approve US operations from its bases under a “very, very clear set of instructions” tied strictly to national interest and defence.

UK officials ‘tying themselves in knots’

However, concerns of complicity had reportedly shaped earlier decisions, according to Tim Ripley, editor of the Defence Eye news service, who said the British government initially concluded that US and Israeli strikes on Iran did not meet the legal definition of self-defence under the United Nations Charter.

When Washington requested the use of bases such as RAF Fairford in Gloucestershire, UK, and Diego Garcia in the Indian Ocean, Starmer is understood to have consulted government lawyers, who advised against participation.

Up until Starmer’s televised address, in which he approved the US request, the UK had not considered the campaign a war of self-defence, said Ripley. While Washington’s legal reasoning has not changed, the war’s trajectory has.

Iranian retaliatory strikes – which have seen drones and missiles targeting Gulf states – have placed British expatriates and treaty partners under direct threat.

“The basis of our decision is the collective self-defence of longstanding friends and allies, and protecting British lives. This is in line with international law,” Starmer said.

According to Ripley, several Gulf governments, which maintain defence relationships with the UK, sought protection, allowing London to focus on protecting British personnel and partners rather than endorsing a broader campaign. However, with memories of the Iraq War hanging over Westminster, British ministers have stopped short of explicitly backing the US bombing campaign.

British officials are “tying themselves in knots” trying to describe a position that is neither fully participatory nor detached, he said.

US-UK: A strained relationship

Starmer on Monday told Parliament that the UK does not believe in “regime change from the skies” but supports the idea of defensive action.

But Ripley warned that any arrangement allowing US warplanes to operate from British air bases carries significant risks.

Iran’s missile systems are mobile and launchers mounted on trucks, he said. From RAF Fairford or Diego Garcia, US aircraft face flight times of seven to nine hours to reach Iranian airspace, necessitating patrol-based missions.

Once airborne, pilots may have only minutes to act. The idea that a US crew would pause mid-mission to seek fresh British legal approval is unrealistic, he said.

London must rely on Washington’s assurance that only agreed categories of “defensive” targets will be struck. If an opportunity arose to eliminate a senior Iranian commander in the same operational zone, the temptation could be strong. Yet such a strike might fall outside Britain’s stated defensive mandate. The aircraft would have departed from British soil, and any escalation could implicate the UK, Ripley said.

Bell highlighted another weakness: Britain has no domestic ballistic missile defence system.

If a ballistic missile were fired at London, he said, “We would not be able to shoot it down.”

Intercepting such weapons after launch is notoriously difficult, reinforcing the argument that the only reliable defence is to strike before launch.

The UK, therefore, occupies a grey zone: legally cautious, operationally exposed and strategically dependent on US decisions, it does not fully control.

Beyond the legal and military dilemmas, Starmer must also contend with a sceptical public.

A YouGov poll conducted on February 20 found that 58 percent of Britons oppose allowing the US to launch air strikes on Iran from UK bases, including 38 percent who strongly oppose.

Just 21 percent support such a move, underscoring limited domestic backing for deeper involvement.

Authorities in Tehran have called for international action and solidarity after several hospitals and schools were impacted by United States and Israeli air strikes on the country as Iran continues to fire missiles and drones across the region.

Iranian Ministry of Foreign Affairs spokesman Esmaeil Baghaei said on Monday that the two countries “continue to indiscriminately strike residential areas, sparing neither hospitals, schools, Red Crescent facilities, nor cultural monuments”.

“These actions constitute the deliberate commission of the most heinous crimes of international concern. Indifference to this ongoing and extreme injustice will only further darken the future of humanity by jeopardising the shared values upon which our global community stands,” he wrote in a post on social media.

Pir Hossein Kolivand, the head of the Iranian Red Crescent Society, wrote a letter publicised late on Sunday to the president of the International Committee of the Red Cross (ICRC), demanding an explicit condemnation of attacks impacting children and educational and medical centres.

He also said monitoring and support mechanisms outlined in the Geneva Conventions must be invoked, adding that the ICRC must “adopt immediate measures” to stop similar incidents from taking place again as the war rages.

“The Red Crescent Society of the Islamic Republic of Iran, as a member of the global Red Cross and Red Crescent movement, declares its full commitment to the fundamentals of humanity, impartiality and independence, emphasising that damaged centres had no military applications,” Kolivand wrote.

ICRC President Mirjana Spoljaric said in a statement at the start of the war on Saturday that rules of war must be upheld as an obligation, not a choice.

“Civilian infrastructure such as hospitals, homes and schools must be spared from attack. Medical personnel and first responders must be allowed to carry out their work safely,” she said.

Hospitals sustain damage

Multiple Iranian hospitals have been damaged as a result of air attacks and were evacuated by authorities, but there are not believed to have been any direct strikes on any hospitals yet.

In Tehran, major strikes on Sunday damaged multiple medical centres located in two areas, according to official accounts, footage circulating on social media and information geolocated by Al Jazeera.

Videos broadcast by state media from the entrance and surrounding area of Gandhi Hospital in northern Tehran showed significant damage after a projectile struck a nearby area.

Mohammad Raeiszadeh, the head of Iran’s Medical Council, told state media from the hospital on Monday that the in-vitro fertilisation department was destroyed along with its equipment, forcing staff to move cells and embryos. Footage also showed an infant being moved by nurses on Sunday night.

The hospital appears to have been damaged after the Israeli military struck buildings housing Iranian state television’s Channel 2 and a communications antenna nearby.

This led to state television programmes being disrupted for several minutes. The broadcaster confirmed that some of its departments were bombed on Sunday without divulging details.

World Health Organization Director General Tedros Adhanom Ghebreyesus said reports of damage to the hospital are “extremely worrying” and the United Nations agency is working to verify the incident.

After a separate attack on Sunday, the Iranian Red Crescent Society released a video showing the aftermath of strikes near one of its main buildings located near Khatam al-Anbiya Hospital.

[Translation: Right now. Direct attacks by the Zionist regime and America on the vicinity of the Red Crescent building, Khatam al-Anbiya Hospital, Welfare Organisation, and Motahari Hospital in Tehran]

Footage circulating online showed plumes of smoke rising and debris scattered after the strikes. According to the Red Crescent, the ICRC’s Spoljaric visited the site of the damaged medical treatment facility on Monday and condemned any strikes impacting humanitarian centres.

Khatam al-Anbiya Hospital, the Motahari Hospital specialising in helping burn victims and the Valiasr Hospital are all located nearby. They reported either sustaining some damage or having to hurriedly move patients out.

The main target hit by Israeli warplanes in the area appeared to have been the central headquarters of the Iranian police. Police Chief Ahmad-Reza Radan did not comment specifically on the targeting of the headquarters but confirmed that police buildings were receiving regular direct hits.

On Monday afternoon, fighter jets conducted bombing runs across Tehran once again. Attacks damaged the main building of the province’s medical emergency services, located in Iranshahr Street in the downtown area. Videos released by state-affiliated media showed staff evacuating, and the state-run Tasnim news agency said several staff members were injured.

According to Iranian authorities, the Aboozar Children’s Hospital in western Iran’s Ahvaz and three medical emergency centres in the provinces of East Azerbaijan, Sistan-Baluchistan and Hamedan were also damaged.

The Iranian Red Crescent said that by noon on Monday at least 555 people had been killed after 131 counties across the country were attacked.

During and after the killing of thousands of people during January’s nationwide protests, Iranian authorities have consistently rejected calls for transparency and condemnations by the UN and international human rights organisations for attacks on hospitals by state forces to detain protesters and medical staff helping the wounded. A number of doctors and medical personnel remain incarcerated and face national security and other charges.

Schools, sports centre take hits

In Tehran, an air strike targeting 72 Square in the eastern neighbourhood of Narmak damaged a high school with authorities reporting that at least two children were killed.

Local media said the target of the attack was Mahmoud Ahmadinejad, the former populist president who may potentially have a role in shaping Iran’s political future after the killing of 86-year-old Supreme Leader Ali Khamenei and other officials. It was unclear whether Ahmadinejad was present at the site of the attack or was harmed.

There were also multiple casualties after a sports centre was targeted in Lamerd in the southern province of Fars, local authorities said on Saturday.

But the single largest casualty incident announced by Iranian authorities was from a girls school in the southern city of Minab.

After two days of working through the debris, authorities said 165 people were killed and 95 wounded, most of them children. The governor on Monday afternoon released a handwritten list of 56 of the victims but did not provide further information.

The US said it was aware of civilian casualty reports from the school and was investigating. The Israeli army said it was not aware of any Israeli or US strikes in that area.

Education International, a global federation that brings together organisations of teachers and other education employees, condemned the school attack.

“Children, teachers, and schools must never be military targets. The killing and wounding of students and educators is an intolerable violation of human rights and a grave breach of international humanitarian law,” it said.

Blaming Iran for previous attacks on Americans in the region, US Secretary of Defense Pete Hegseth says Washington didn’t start the war, but under President Donald Trump, “we’re finishing it”.

Members of Nigeria’s Shia Muslim community are mourning Iran’s Supreme Leader Ayatollah Ali Khamenei who was killed by a US-Israeli attack in Tehran. Demonstrators carried his portrait and waved Iranian flags while they dragged American and Israeli flags along the ground.
