The U.S. military announced that, starting at 14:00 GMT on Monday, it will enforce a blockade of every Iranian port, a step taken after President Donald Trump ordered a naval closure of the Strait of Hormuz—the waterway through which roughly one‑fifth of global crude oil normally flows. The blockade comes on the heels of stalled peace negotiations in Islamabad, where talks between Washington and Tehran collapsed without an agreement despite a prior cease‑fire pledge. Trump’s escalation has already driven crude prices above $100 per barrel and unsettled Asian equity markets, with the Nikkei 225 down 0.84%, the Topix slipping 0.42% and South Korea’s Kospi falling 1.83%. Iran’s response is equally forceful. The Islamic Revolutionary Guard Corps warned that any vessel entering the strait would be deemed a breach of the cease‑fire and dealt with “harshly and decisively,” insisting it has “full control” and threatening a “deadly vortex” for any misstep. Navy chief Shahram Irani dismissed Trump’s threat as “ridiculous and funny,” while state television said Iranian forces are closely monitoring U.S. movements. Foreign Minister Abbas Araghchi lamented “maximalism, shifting goalposts, and blockade” that undermined a near‑final Islamabad memorandum, quoting, “Good will begets good will. Enmity begets enmity.” Parliament speaker Mohammad Bagher Ghalibaf pledged resistance and mocked U.S. gasoline prices, posting a map of Washington‑area pump prices and predicting nostalgia for $4‑$5 gas. U.S. Central Command clarified that the blockade will stop all vessels bound for or from Iran, while traffic to non‑Iranian ports will continue unhindered. Trump also warned that any ship that has paid an “illegal toll” to Iran will be intercepted on the high seas, and he publicly criticized Pope Leo XIV for urging an end to the conflict. In Lebanon, Israeli airstrikes have killed at least five people, bringing the country’s overall death toll to 2,055. Hezbollah retaliated with a rocket barrage aimed at northern Israeli towns, citing violations of a cease‑fire. The United Nations Interim Force in Lebanon (UNIFIL) reported that an Israeli tank rammed peace‑keeping vehicles twice in the south. Israel’s Prime Minister Benjamin Netanyahu visited troops on the Lebanese border, claiming that Hezbollah’s invasion threat has been neutralized, though he acknowledged that hostilities continue within the security zone. On the energy front, shipping through the Hormuz corridor has “immediately halted,” according to Lloyd’s List, with several vessels turning back after the blockade announcement, further tightening global oil supplies.

Australia announced that Lieutenant General Susan Coyle will assume the role of chief of the Australian Army in July, marking the first time a woman has held the post in the service’s 125‑year history.Coyle, currently chief of joint capabilities, brings nearly four decades of experience, including senior command roles in Afghanistan and the Middle East, and expertise in cyber‑warfare. She will succeed Lieutenant General Simon Stuart, who took the position in July 2022.Prime Minister Anthony Albanese hailed the appointment as a historic breakthrough, stating, "From July, we will have the first ever female chief of army in the Australian Army’s 125‑year history." Defence Minister Richard Marles called the move a "deeply historic moment" and emphasized its symbolic power: "You cannot be what you cannot see."The appointment arrives as the Australian Defence Force (ADF) intensifies efforts to raise female participation. Women currently constitute about 21 % of the ADF and 18.5 % of senior leadership roles, with a target of 25 % overall participation by 2030.In October, a class‑action lawsuit alleged that the ADF failed to protect thousands of women officers from systematic sexual assault, harassment, and discrimination, underscoring the urgency of cultural reform alongside the leadership change.Alongside Coyle’s promotion, Vice Admiral Mark Hammond, the incumbent chief of the navy, will become the head of the ADF, succeeding Admiral David Johnston. Rear Admiral Matthew Buckley is set to replace Hammond as navy chief.The army is also undergoing a major transformation, investing in long‑range firepower, drones, and other modern combat tools. Coyle’s background in cyber‑warfare is expected to bolster the force’s capability to operate in increasingly digitised battlefields.

President Donald Trump has signaled that the U.S. Navy will enforce a blockade of the Strait of Hormuz, targeting any vessel that has paid a toll to Iran. The announcement sent oil futures soaring past $100 per barrel on Monday, reviving fears of a deeper global energy crisis. U.S. Central Command later clarified that the operation would focus on ships entering or leaving Iranian ports, a narrower scope than the initial threat to shut the entire strait. Nonetheless, experts say the move would still choke a critical chokepoint in world oil supply. "Anything that removes oil from the market pushes prices higher, which in turn lifts gasoline costs," explained Trita Parsi, co‑founder of the Quincy Institute. He warned that if Iran’s allies, notably the Houthis in Yemen, retaliate by closing the Bab al‑Mandeb strait, oil could surge above $150 a barrel. Bab al‑Mandeb serves as an alternative route for Gulf oil to reach the Red Sea and Indian Ocean. Its closure would compound the disruption already caused by the Hormuz threat. Since the start of the U.S.–Israeli conflict on February 28, Iran has limited traffic through Hormuz, allowing only a handful of vetted ships. Windward estimates that about 3,200 vessels were stranded west of the strait as of Saturday. Former chief economist Anas Alhajji of NGP Energy Capital Management expects non‑Iranian carriers to avoid the strait regardless of U.S. assurances, citing rising insurance premiums and the risk of Iranian retaliation. "The Trump blockade of Iranian ports is effectively a blockade of the Hormuz Strait," he told Al Jazeera. The ripple effects extend beyond fuel. Higher oil and gas prices will lift the cost of chemicals, fertilizers and plastics feedstocks, analysts say. Cameron Johnson, senior partner at Tidalwave Solutions, predicts a rapid increase in raw‑material prices if the blockade persists into late April or early May. "The wild card is the timeframe," Johnson noted. "If it’s a short‑term negotiating tactic, the market may absorb it, but a prolonged blockade will spike global commodity prices." Supply‑chain experts warn of broader repercussions. Deborah Elms of the Hinrich Foundation highlighted that rising fabric costs and packaging shortages could strain food production and consumer goods later in the year. Industry observer Chad Norville of Rigzone said the mere threat erodes confidence in the strait’s stability, likely driving up insurance costs and reducing daily trade volumes. In sum, a U.S. blockade of Iranian ports would mark a stark reversal of recent policy, which had briefly eased sanctions to alleviate the energy crunch. The potential escalation underscores how geopolitical moves can quickly translate into higher energy bills and broader economic strain worldwide.

The National Gallery of Art's latest exhibition, 'Dear America: Artists Explore the American Experience', is a thought-provoking collection of over 100 works by 95 artists. This 'open letter to the nation' offers a multifaceted exploration of the American experience, delving into themes of land, community, and freedom.Upon entering the exhibition, visitors are immediately struck by the unconventional representations of iconic American symbols. The Statue of Liberty, for instance, is reimagined through the lens of South African photographer Zanele Muholi and a geometric screenprint by Roy Lichtenstein.The exhibition's curatorial approach is to create 'provocative conversations across centuries, disciplines and demographics.' E Carmen Ramos, the gallery's chief curatorial and conservation officer, notes that the show was 'years in the making' and showcases an 'embarrassment of riches' from the gallery's permanent collection of over 160,000 works.Structured around three core themes – land, community, and freedom – the exhibition presents a diverse array of works. These include Thomas Moran's idyllic watercolours of the American West juxtaposed with Thomas Hart Johnson's photographs of a landscape ravaged by coal mining and railroads. The exhibition also features poignant pieces such as Carrie Mae Weems's haunting silhouette and Gordon Parks's indelible 'American Gothic.'The show's second section, 'Community,' features Richard Avedon's massive 1976 commission 'The Family,' which comprises 69 stark, uniform portraits of the bicentennial era's political, media, and corporate elite. This is contrasted with John Wilson's tender sketches of his teenage children and their friends.The final act of the exhibition turns its lens to 'Freedom,' showcasing historical portraits of figures such as Frederick Douglass, Sojourner Truth, and George Washington, alongside powerful works by Kara Walker, Martha Rosler, and Faith Ringgold. As visitors exit, they are met with Robert Indiana's boldly coloured screenprint 'Liberty '76,' created for the 1976 bicentennial.Ramos reflects on the exhibition's significance, stating that it 'explores how artists in the United States have explored the American experience across different moments in time.' The exhibition will be on view in the National Gallery's West Building until 20 September.

A French court has fined Lafarge, a French cement maker, more than €1m (£870,000) and sentenced its former boss, Bruno Lafont, to six years in prison for paying protection money to Islamic State and other terror groups to maintain its business in war-torn Syria from 2013 to 2014.The ruling follows a 2022 case in the United States in which Lafarge pleaded guilty to conspiring to provide material support to US-designated “terrorist” organisations and agreed to pay a $778m fine (£580m). This was the first time a company had faced the charge.The Paris court found that Lafarge, which is now part of the Swiss conglomerate Holcim, paid nearly €5.6m via its subsidiary Lafarge Cement Syria (LCS) to terror groups and intermediaries to keep its plant operating in northern Syria.The company’s former chief executive, Bruno Lafont, was sentenced to six years in prison for financing terrorism, which a judge ordered him to start serving immediately. Lafont’s lawyer said he would appeal.The presiding judge, Isabelle Prevost-Desprez, said: “This method of financing terrorist organisations, and primarily IS, was essential in enabling the terrorist organisation to gain control of Syria’s natural resources, allowing it to finance terrorist acts within the region and those planned abroad, particularly in Europe.”Lafarge established a “genuine commercial partnership with IS”, she said, which added to the “extreme gravity of the offences”.Lafarge had finished building a $680m factory in Jalabiya in 2010, just before Syria’s civil war erupted in March the following year amid opposition to the brutal repression of anti-government protests by the then president, Bashar al-Assad.While other multinational companies left Syria in 2012, Lafarge evacuated only its expatriate employees and left its Syrian staff in place until September 2014, when IS seized control of the factory.In 2013 and 2014, LCS paid intermediaries to access raw materials from the Islamic State organisation and other groups and to allow free movement for the company’s trucks and employees. It paid groups including Islamic State and Syria’s then al-Qaida affiliate Jabhat al-Nusra.

For the first time, thousands of cancer patients from Black and minority ethnic backgrounds will benefit from an enhanced genetic test offered by the NHS. The new screening expands the panel of DPYD gene variants from four to five, directly addressing a long‑standing bias that left non‑white patients vulnerable to dangerous chemotherapy side‑effects. In England, patients slated for chemotherapy undergo a genetic check that can guide dose adjustments and mitigate adverse reactions such as mouth sores, hair loss, nausea, fatigue, and, in severe cases, death. Up to 40% of the 38,000 individuals receiving fluoropyrimidine‑based chemotherapy each year experience a harmful drug reaction. Previously, the test only targeted four DPYD variants common in people of European descent, meaning many Black patients received inaccurate “all‑clear” results. The addition of a fifth variant—more prevalent among African, Caribbean and other minority groups—means clinicians can now identify patients at risk who were previously missed. Since its rollout at Manchester University NHS Foundation Trust last September, three minority‑ethnic patients have had their initial chemotherapy doses adjusted, lowering their chance of a potentially fatal reaction. Dr Veline L’Esperance, senior clinical adviser at the NHS Race and Health Observatory, called the change “tangible results for patients who have historically been left behind.” She emphasized that the update shifts the discussion on ethnic health inequality from rhetoric to actionable care. Prof Habib Naqvi, chief executive of the NHS Race and Health Observatory, described the development as a “groundbreaking outcome” for chemotherapy safety, while noting that ethnic minorities remain under‑represented in genomic research and biobanks. He warned that broader inclusion is essential for the promised benefits of precision medicine to reach all communities. Prof Dame Sue Hill, chief scientific officer for NHS England, highlighted the significance of discovering the fifth variant: “Personalising chemotherapy based on genetics can save lives and reduce harmful side‑effects, especially for patients of African ancestry.” She added that the North West NHS Genomic Medicine Service has already demonstrated the practical impact of this approach. These steps come amid broader evidence that minority patients in the UK face longer diagnostic waits, more GP visits before a cancer diagnosis, and lower perceived support during treatment. The expanded DPYD test represents a concrete effort to close those gaps and ensure equitable, science‑driven care for all cancer patients.

At 19,000 miles above the lunar surface, the Artemis II astronauts heard the voice of Apollo‑13 commander Jim Lovell greeting them from beyond the grave, a message recorded shortly before his death at 97. Mission control transmitted the tribute on the morning of 6 April, when astronaut Reid Wiseman held a silk square bearing the original Apollo 8 patch—handed to him by Lovell’s son—before the crew’s launch. Launch director Charlie Blackwell‑Thompson secured a unanimous "go" from every console, a moment the author describes as a snapshot of humanity’s capacity to honor the past while reaching for the future. The ceremony stood in stark contrast to the Pentagon’s agenda. Two decades after a 2006 Iraqi kill‑board note reading “Let the bodies hit the floor,” the current defense chief pledged “death and destruction from the sky all day long” against Iran, a stance legal scholars warn could constitute a war crime. That rhetoric accompanies a proposed $1.5 trillion defense budget, including an additional $200 billion earmarked for operations against Iran—figures that dwarf NASA’s entire annual budget of $24.4 billion. Amid this fiscal disparity, crew members reflected on their place in history. Victor Glover, the first Black astronaut to travel deep space, described the view of Earth as an "oasis" in the void, while Christina Koch, the first woman to orbit the Moon, pressed her face to the window and formed a heart with her hands, calling the mission’s spirit "humility." Reid Wiseman watched the planet rotate beneath him, noting the sight of Africa, Europe, and the aurora‑lit north, saying it "paused all four of us in our tracks." Canadian astronaut Jeremy Hansen broke Jim Lovell’s 56‑year distance record and asked mission control to name a lunar feature after his late wife, Carroll. The crew agreed, designating a bright spot on the Moon as "Carroll," a tribute that will endure beyond any single lifetime. When Koch announced the spacecraft’s descent, she radioed, "We are now falling to the moon rather than rising away from Earth," a poetic reversal that underscored the mission’s symbolic return. The article recalls the author’s 2022 reflection on the James Webb Space Telescope, noting how humanity’s finest inventions now aim outward, seeking answers to our origins rather than turning inward toward conflict. Artemis II’s vessel, named Integrity, carried four breathing humans who, in a moment of collective grief, pressed their faces to the glass and imagined the faces of every loved one ever lived, captured in a single frame. Beyond the spacecraft, cultural threads wove through the mission: Hansen’s patch displayed the Seven Sacred Teachings of the Anishinaabe people, and the Chinese myth of Chang’e reminded viewers of the Moon’s timeless allure. As Carl Sagan famously wrote, "We are made of star‑stuff," the Artemis crew embodied that sentiment—not as passive observers, but as active participants in a fragile, hopeful narrative that rises above the relentless tally of bodies on Earth’s battlefields.

Goldman Sachs's chief executive, David Solomon, has expressed heightened awareness of the capabilities of Anthropic's Mythos AI model and is collaborating closely with the tech firm following warnings about the cybersecurity risk it poses.The US bank has been closely monitoring the rapid advancements in artificial intelligence, including large language models (LLMs), as part of broader efforts to protect itself from hackers.“Obviously the LLMs are making rapid progress and we’re hyper-aware of the enhanced capabilities of these new models with the help of the US government and the model publishers,” Solomon told analysts on an earnings call on Monday.Anthropic, the company behind the Claude family of AI tools, claimed last week that its latest model, Mythos, posed an unprecedented risk due to its ability to expose flaws in IT systems. The company warned that AI models have reached a level of coding capability where they can surpass all but the most skilled humans at finding and exploiting software vulnerabilities.Solomon emphasized that Goldman Sachs is working closely with Anthropic and all of its security vendors to harness frontier capabilities. “We are very focused on supplementing our cyber and infrastructure resilience. And this is part of our ongoing capabilities that we have been investing in, and are accelerating our investment in.”The news comes after the US Treasury secretary, Scott Bessent, summoned Solomon and other big American bankers to Washington to discuss the Mythos model last week. The meeting focused on heads of so-called systemically important banks, where regulators believe that a major disruption to their operations, or their potential collapse, would put financial stability at risk.On Monday, the UK government’s AI Security Institute (AISI) warned that Mythos was a “step up” over previous models in terms of the cyber threat it posed. AISI said Mythos could carry out attacks that required multiple actions and discover weaknesses in IT systems without human intervention.

World champion boxer Terence Crawford was found guilty of careless driving on Monday and ordered to pay a $75 fine stemming from a traffic stop last year that led to a gunpoint incident. The incident occurred on September 28, hours after Crawford's hometown of Omaha held a parade to celebrate his unanimous-decision victory over Canelo Álvarez in a super middleweight championship fight.Crawford was stopped by police after officers observed his vehicle driving recklessly. During the stop, Crawford's head of security informed an officer that he was carrying a legal firearm, and seconds later, another officer spotted a gun on the floorboard. With guns drawn, officers ordered everyone out of the vehicle. Crawford claimed he had leaned over to tell the officer that he also had a legal firearm, but the officer didn't hear him. Police confirmed that all occupants of the vehicle were legally permitted to carry firearms.The traffic stop led to an internal investigation by the Omaha police chief into the officers' actions, which was found to have been lawful. In addition to the $75 fine, Crawford was ordered to pay $49 in court costs. This incident comes after Crawford announced his retirement in December with a 42-0 record and 31 knockouts, making him the first male boxer to capture three unified division titles.
