Iranian officials have urged young people to form human chains around the country's power plants, as tensions escalate with the US and Israel. The call to action comes as US President Donald Trump threatens massive strikes on civilian infrastructure if Iran doesn't reopen the Strait of Hormuz.Iranian media showed people gathering outside electricity stations, waving Iranian flags and holding up banners. In Dezful, people gathered on a 1,700-year-old bridge. The country's president, Masoud Pezeshkian, said 14 million people had signed up to fight for their country and declared their readiness to sacrifice their lives in defence of Iran.The US and Israel carried out waves of preparatory strikes that appeared to knock off course the chances of a last-minute ceasefire deal before Trump's 8pm ET (1am BST) deadline for Iran to reopen the strait. Attacks on civilian infrastructure amount to war crimes, legal experts say.Alireza Rahimi, identified by Iranian state television as the secretary of the Supreme Council of Youth and Adolescents, issued a video message calling on young people to form human chains around power plants. He asked them to gather on Tuesday at 2pm around the power plants, which he described as national assets and capital.Iran has formed human-chain demonstrations, also known as human shields, in the past around its nuclear sites at times of heightened tensions with the west. A man in Tehran said his household had collected basic necessities and equipment to charge their mobile phones, in preparation to flee the capital if necessary.The indirect negotiations between the US and Iran are continuing, largely by passing messages through Pakistan. However, the intermediaries said they feared that Israel was bombing the chances of reaching an agreement.

The ongoing conflict between the US and Iran has raised concerns about the protection of civilians in war. Donald Trump's threats to bomb civilian infrastructure, including power stations, desalination plants, and bridges, have been widely criticized as potential war crimes. In a recent statement, Trump doubled down on his threat, saying that a whole civilization will die if his demands are not met. This rhetoric has sparked fears of a humanitarian crisis and raised questions about the US's commitment to protecting civilians in war.Historically, the protection of civilians has been a cornerstone of international law. The Geneva Conventions, established in 1949, clearly state that civilian objects shall not be the object of attack or reprisals. The US has a long tradition of upholding these principles, dating back to the Lieber Code of 1863, which established protocols for the protection of the innocent during the Civil War.The article argues that protecting civilians is not a sign of weakness, but rather a sign of strength and self-discipline. It cites examples of leaders who have prioritized humanitarian concerns in times of war, including President Franklin D. Roosevelt's vision for a world united around democratic values and international organizations. In contrast, Trump's approach has been criticized for its lack of nuance and disregard for humanitarian concerns. The article notes that the US must distinguish between military targets and civilian infrastructure, and that cyber-attacks and other non-lethal methods should be used whenever possible to minimize harm to civilians.Ultimately, the article concludes that upholding American values and international law is essential to maintaining global stability and preventing humanitarian crises. By prioritizing the protection of civilians, the US can demonstrate its commitment to humanitarian principles and show that it is capable of fighting wars with greater purpose and a plan for peace.

Tens of thousands of people have been hired by Scale AI – a firm 49% owned by Meta – to train artificial‑intelligence models by scraping Instagram accounts, harvesting copyrighted artwork and transcribing pornographic soundtracks, according to the Guardian.Scale AI promotes its Outlier platform as a flexible, expert‑driven marketplace, recruiting professionals from medicine, physics and economics to "become the expert that AI learns from."Workers, however, say the reality diverges sharply from high‑level model refinement. They describe tasks that involve massive personal‑data scraping and content that many find morally uncomfortable.Outlier is managed by Scale AI, which holds contracts with the U.S. Pentagon and other defense companies. Its chief executive, Alexandr Wang, is hailed by Forbes as the world’s youngest self‑made billionaire, while former managing director Michael Kratsios served as science adviser to former President Donald Trump.One contractor noted that users of Meta platforms would be shocked to learn their photos and friends’ images are being harvested for AI training, with workers manually reviewing profiles to extract data.The Guardian interviewed ten Outlier contributors – many also journalists, graduate students, teachers or librarians – who took the gig work out of economic desperation. One said, "A lot of us were really desperate" and felt compelled to accept the unstable, low‑pay assignments.These gig workers, dubbed “taskers,” often feel they are training their own replacements, expressing “internalised shame and guilt” over contributing to the automation of creative professions.Law firm Clarkson, representing AI gig workers, estimates that hundreds of thousands of people worldwide now labor on platforms like Outlier. Taskers report bait‑and‑switch recruitment tactics, where advertised high salaries are replaced by lower‑paid projects after onboarding.All contributors are monitored through a tool called Hubstaff, which can screenshot browsers to verify work. While Scale AI claims the software is only for accurate payment, workers describe it as constant surveillance.Assignments have ranged from transcribing pornographic audio and labeling photos of dead animals or dog faeces, to annotating diagrams of infant genitalia and violent police scenarios. One doctoral student recounted being promised “no nudity” only to receive explicit porn clips.Scale AI says it shuts down any task flagged as inappropriate and does not accept projects involving child sexual‑abuse material or pornography, though workers note that publicly available images of minors have been used for training.Social‑media scraping tasks required workers to tag individuals by name, location and age, sometimes pulling data from accounts of users under 18. One task asked contributors to order Facebook photos by the subject’s age, prompting ethical unease.In addition to personal data, taskers were asked to harvest copyrighted artwork, with strict instructions to avoid AI‑generated images and select only hand‑drawn pieces. Scale AI maintains it does not ask workers to violate copyright standards.Scale AI’s client list includes major tech firms such as Google, Meta and OpenAI, as well as the U.S. Department of Defense and the government of Qatar, highlighting the growing demand for labelled data as AI models scale.Some workers reported interacting with ChatGPT and Claude, and speculated they might be training Meta’s upcoming model, code‑named “Avocado.”OpenAI announced it ended its partnership with Scale AI in June 2025, citing its supplier code of conduct that mandates ethical treatment of all workers.Despite irregular pay, occasional mass layoffs and the unsettling nature of many tasks, many taskers remain on the Outlier platform, hoping the AI future will eventually improve conditions. One said, "I have to be positive about AI because the alternative is not great."In response, a Scale AI spokesperson stated, "Outlier provides flexible, project‑based work with transparent pay. Contributors choose when and how they participate, and we regularly hear from highly skilled contributors who value the flexibility and opportunity to apply their expertise on the platform."

The International Monetary Fund (IMF) has issued a warning that emerging economies are facing a heightened risk of financial instability due to their increased reliance on market-based finance, particularly from hedge funds and investment funds. A cumulative $4tn flowed into emerging markets last year from outside the formal banking sector, which can bring benefits but also poses significant risks.The IMF's analysis suggests that this type of financing can be more volatile than traditional bank financing and is more likely to be withdrawn suddenly in times of financial stress. This can lead to abrupt retrenchments, intensify external financing pressures, raise borrowing costs, and trigger sharp currency depreciations, ultimately weighing on economic growth.The IMF highlights that some countries are already experiencing these challenges, particularly in the context of the war in the Middle East. Several emerging markets are experiencing a reversal of capital flows from non-resident non-bank investors, which can have a significant impact on their economies.The IMF also notes that hedge funds and mutual funds have the highest propensity to withdraw during market volatility, while pension funds and insurers tend to be more cautious. Additionally, the IMF warns about the growing flows of stablecoins into emerging economies, which can be vulnerable to wider fluctuations in cryptocurrency markets.The IMF's managing director, Kristalina Georgieva, warned that the conflict will lead to higher prices and slower growth, adding that even if the war were to stop today, there would be a lingering negative impact on the rest of the world.

Match details: Real Madrid will host Bayern Munich at the Santiago Bernabeu on Tuesday, 7 April, kick‑off at 21:00 GMT, in the first leg of the Champions League quarter‑finals. Bayern, under Vincent Kompany, arrive in Madrid riding a wave of confidence, having dispatched Atalanta 10‑2 on aggregate in the last‑16 and gone 14 matches without defeat since a January loss. Harry Kane’s potential comeback adds extra intrigue. The England striker, who has netted 48 goals in 40 games across all competitions this season, missed Bayern’s 3‑2 Bundesliga win at Freiburg with an ankle problem. Joshua Kimmich quipped that Kane “would play in a wheelchair,” while Kompany expressed a “feeling” that the striker will be fit for Tuesday. Despite Real’s storied pedigree – 15‑time European champions featuring stars such as Kylian Mbappé, Vinícius Júnior and Jude Bellingham – many analysts view Bayern as the slight favourites, citing their aggressive, high‑pressing approach and the recent form of newcomers Michael Olise and Luis Diaz. Real Madrid, meanwhile, grapple with a spate of injuries. Thibaut Courtois is sidelined with a thigh issue, handing Andriy Lunin the starting goalkeeper role. Rodrygo is also out, while Ferland Mendy and Dani Ceballos remain doubtful. Midfielder Federico Valverde is expected back after serving a suspension, and Jude Bellingham may start on the bench as he recovers from a hamstring strain. Coach Álvaro Arbeloa downplayed the recent La Liga defeat to Mallorca, insisting it will not affect the team’s performance in Europe. He stated, “I know what my players are capable of, and they understand the importance of Tuesday’s game.” Bayern’s side will also miss several players through injury – goalkeepers Sven Ulreich and others – while a final fitness test will determine whether Kane can lead the line. If he is unavailable, Nicolas Jackson is slated to spearhead the attack. Predicted line‑ups (subject to change):Real Madrid – Lunin; Alexander‑Arnold, Rüdiger, Huijsen, Carreras; Valverde, Tchouaméni, Pitarch, Güler; Mbappé, Vinícius Jr.Bayern Munich – Neuer; Stanisic, Upamecano, Tah, Laimer; Kimmich, Goretzka; Olise, Gnabry, Díaz; Kane. The Bernabeu atmosphere is expected to be a decisive factor. Bayern veteran Karl‑Heinz Rummenigge warned that the stadium’s “hurricane” of fans demands “nerves of steel” from both sides. Historically, the two clubs have met 28 times, each securing 12 victories with four draws. Recent head‑to‑head encounters have favored Madrid, including a 2‑1 win in the 2024 semi‑finals. Bayern hope to rewrite that narrative after their 2012 triumph over the Spanish giants. With both teams boasting a blend of experience and emerging talent, the first leg promises a tactical battle that could set the tone for the remainder of the tournament.

President Donald Trump issued an ultimatum demanding that Iran reopen the Strait of Hormuz by 8 p.m. Eastern Time on April 7 (midnight GMT on April 8) or face the destruction of national power plants and major bridges.This demand mirrors a March 21 warning in which Trump threatened to strike Iran’s power plants – “the biggest one first” – if the waterway was not fully reopened within 48 hours.Since then, the deadline has been extended several times, with the White House citing progress in secret negotiations aimed at ending the ongoing conflict, a claim Iran publicly denies.While Trump has repeatedly declared that Iran would “lose every power plant and every other plant they have in the whole country,” he has not identified specific facilities as targets.The president has also threatened to demolish Iran’s bridges; a recent U.S.–Israeli strike damaged the B1 bridge in Karaj, a high‑profile structure slated for inauguration, underscoring the tangible risk to civilian infrastructure.Legal analysts warn that such attacks could constitute “collective punishment,” a practice prohibited under international humanitarian law.Iran’s electricity network comprises hundreds of power stations that together form one of the Middle East’s largest grids, supplying power to approximately 92 million people. Most facilities cluster around major population centres—Tehran, Mashhad, and Isfahan—where demand is highest.The generation mix is dominated by natural‑gas‑fired plants, supplemented by coal, oil, hydro, and a single nuclear facility. In the north and centre of the country, dense clusters of gas‑fired stations serve Tehran, Karaj, Isfahan and Mashhad.Along the Gulf coast, a second concentration of plants benefits from proximity to vast gas fields and ports, enabling large thermal stations to operate on abundant natural gas. This coastal belt also hosts the Bushehr Nuclear Power Plant, Iran’s only nuclear reactor with a capacity of 1,000 MW, a site that has been repeatedly targeted by U.S. and Israeli forces, raising concerns about potential radioactive fallout.Hydropower generation is centred on a series of dams along the Karun River, the country’s primary source of hydroelectric power.All electricity is transmitted through a national grid managed by the Iran Grid Management Company, delivering power to cities, industry and households.A map of Iranian power stations with capacities of 100 MW or more shows that a single 100 MW plant can typically supply electricity to 75,000–100,000 homes, depending on consumption patterns.The nation’s largest facility is the Damavand Power Plant in Pakdasht, about 50 km southeast of Tehran, boasting a capacity of 2,868 MW—enough to energise more than two million homes.Key high‑capacity plants include:Damavand (Pakdasht) – Natural‑gas combined‑cycle, 2,868 MW.Shahid Salimi – Neka, Caspian Sea coast, natural gas, 2,215 MW.Shahid Rajaee – Near Qazvin, natural gas, 2,043 MW.Karun‑3 Dam – Khuzestan Province, hydropower, 2,000 MW.Kerman – Natural gas, 1,912 MW.Other strategically important stations are the Ramin Power Plant (1,903 MW, gas), the Bushehr Nuclear Power Plant (1,000 MW, nuclear), and the Bandar Abbas Power Plant (1,330 MW, oil) near the Strait of Hormuz.Iran’s electricity generation is heavily fossil‑fuel dependent: in 2025, 86 % of power came from natural gas, 7 % from oil‑fired plants, about 5 % from hydropower, 2 % from nuclear, and less than 1 % from solar and wind. This makes Iran one of the world’s most gas‑reliant power systems.Targeting the grid would therefore cripple energy supply for millions, disrupt industrial output, and could trigger a humanitarian crisis, while also escalating geopolitical tensions in an already volatile region.

President Donald Trump opened the traditional Easter Egg Roll on the White House South Lawn alongside a child dressed in a giant bunny costume, before turning the event into a platform for a stark Iran warning to a room of reporters. Hours later, the president entered a packed briefing room flanked by Defence Secretary Pete Hegseth. The press conference highlighted the recent rescue of a U.S. airman whose jet was downed by Iran, a mission Trump praised as "genius" and likened to a Hollywood production. Amid the celebration, Trump shifted focus to a $1.5 trillion Pentagon budget request he had submitted the previous week, emphasizing military spending while domestic programs face cuts. In a chilling turn, the president warned that the United States could "take out the entire country in one night" by targeting Iran’s bridges and power plants, a threat he framed as a potential path to freedom for the Iranian people. He claimed, without evidence, that Iranians would accept such suffering to topple their regime. When a reporter cited the Geneva Conventions, Trump dismissed the concern, questioning the journalist’s affiliation and mocking the New York Times for its declining circulation. Trump also hinted at personal profit, stating, "I'm a businessman first" when asked about seizing Iranian oil, and invoked a quasi‑religious narrative, saying, "God was watching us" during the Easter festivities. Defence Secretary Hegseth, known for his ties to Christian nationalism, likened the rescue to a resurrection, describing the timeline from the aircraft’s downing on Good Friday to its recovery on Easter Sunday as a "pilot reborn". Critics on social media and within Congress have labeled Trump’s rhetoric as "insane" and "dangerous," urging the cabinet to consider the 25th Amendment to assess his fitness for office. The president brushed off mental‑health concerns, suggesting that if his condition were an issue, "you’ll need more people like me." Recent weeks have seen Trump make contradictory statements: first denying the strategic importance of the Strait of Hormuz, then threatening escalation; first boasting of air superiority after a U.S. fighter was shot down, then claiming the war is already won. These erratic pronouncements have heightened worries that the nation’s nuclear launch authority may be in the hands of a leader whose public behavior resembles the "Mad Hatter" of Lewis Carroll’s classic.

At Augusta National, Justin Rose’s name appears twice on the bronze winner’s list beside the victories of Sergio García (2017) and Rory McIlroy (2025) – both wins coming after playoffs that Rose lost. Only Ben Hogan shares the dubious distinction of losing two Masters playoffs, though Hogan later won the tournament twice outright.Rose’s record also includes a second‑place finish in 2015, four strokes behind Jordan Spieth. The only player with more runner‑up finishes without ever winning is Tom Weiskopf, who was second four times in seven years.Now 45 years old and entering his 21st Masters, Rose cannot predict if he will ever get as close again as he did last year, when McIlroy’s birdie putt on the 18th sealed a one‑stroke playoff defeat.“When you realise you’re that close, you can taste the victory,” Rose says. “I lived it as if I’d won, but without the real positive emotion – I sensed everything.” He acknowledges the mental rehearsal of the “what‑if” scenario while maintaining that he “did everything he could” and can live with the result.Rose explains his mental formula: “You can’t make a major win too important in the moment,” because a career inevitably includes “a little bit of heart‑ache and heartbreak.” He believes that to win, a player must also be prepared to be on the losing side.Despite the setbacks, Rose feels he has already demonstrated the necessary skill set. “I’ve pretty much done what it takes to win. I just haven’t walked over the line,” he asserts, emphasizing that he does not feel the need to change his approach.Recent form offers optimism. Earlier this year Rose set a new course record at Torrey Pines and became the first player in 71 years to win the Farmers Insurance Open wire‑to‑wire. He notes that eight players have captured the Masters after finishing second the previous year, suggesting his odds improve when the field is considered.Rose is also mindful of external narratives. “People are wishing me well and thinking it’s my year,” he admits, adding that he must manage expectations and craft his own story rather than buying into others’ predictions.

Conservationists and scientists have warned that the Minerals Council of Australia’s proposal to employ artificial intelligence for faster national environmental approvals could generate “Robodebt‑style” failures, further endangering already vulnerable species.The council has asked the federal government to allocate $13 million for a pilot that would use AI to help companies draft assessment applications and assist regulators in decision‑making.The Biodiversity Council – a consortium of independent experts from eleven universities – told Guardian Australia that while AI may assist with routine tasks, automating whole environmental assessments could lead to opaque, flawed decisions that push threatened species closer to extinction.“Robodebt” refers to the automated welfare‑debt recovery scheme that, between 2015 and 2019, wrongly accused hundreds of thousands of Australians of overpayments, highlighting the danger of opaque algorithmic judgments.Lis Ashby, the Biodiversity Council’s lead on policy and innovation, noted that the cornerstone of Australia’s environmental protection, the Environment Protection and Biodiversity Conservation (EPBC) Act, is riddled with vague language and broad ministerial discretion, which hampers rule‑based decision‑making and would be even more problematic for an AI tool.She added that establishing clear rules in the National Environmental Standards, including explicit definitions of unacceptable outcomes, would accelerate assessment times even without AI and is essential for any future automation.Brendan Sydes, national biodiversity policy adviser at the Australian Conservation Foundation, expressed scepticism, stating that “technology can be a good servant but a poor master.” He urged the government to focus on closing existing data gaps on threatened species and habitats rather than relying on AI.Prof. David Lindenmayer, a forest ecologist at the Australian National University and Biodiversity Council member, highlighted that one‑third of Australia’s threatened species have not been monitored and many others suffer from patchy data, gaps traditionally filled by expert consultation.He warned that AI decisions are only as reliable as the data they are fed, and most threatened species lack publicly available information, even basic location data, risking decisions based on outdated or incomplete evidence.The Albanese government recently passed reforms to the EPBC Act after a 2020 review found the legislation failing to protect species and habitats.Prof. Hugh Possingham, a leading conservation biologist at the University of Queensland, argued that AI models need robust training material, and the past two decades of EPBC approvals are “clearly unsuitable” because the Act has demonstrably failed to safeguard the environment. He suggested that hiring more human assessors would be a more effective way to speed up evaluations.Tania Constable, chief executive of the Minerals Council, dismissed the Robodebt comparison as “disappointing,” insisting the proposal is innovative and could strengthen environmental protection while improving efficiency. She said the AI tools would support human decision‑making for both regulators and project proponents, helping navigate the complexity of EPBC assessments.A federal government spokesperson said budget decisions on the AI trial will be made “in due course,” but the environment department is exploring how AI could simplify application processes. The statement emphasized that “decisions about whether to approve projects must, and will, always be made by assessment officers, not by AI.”Nonetheless, officials acknowledged that AI tools have the potential to save time, reduce uncertainty, and translate technical language for stakeholders.
