British Prime Minister Keir Starmer declared that the United Kingdom will not participate in the United States’ proposed blockade of the Strait of Hormuz, distancing London from President Donald Trump’s latest escalation against Iran.Speaking on BBC Radio, Starmer said, "We are not supporting the blockade," and added that the UK will not be "dragged into the US‑Israel war on Iran."The Strait of Hormuz is a strategic chokepoint through which about 20 % of the world’s oil supplies transit in peacetime. Starmer stressed that reopening the waterway is vital for global energy security and that the UK’s diplomatic efforts over recent weeks have focused on that goal.Meanwhile, the US Central Command announced it would block all maritime traffic entering or leaving Iranian ports from 14:00 GMT, though it provided few details on how the blockade would be enforced. The statement claimed the action would be applied impartially to vessels of all nations, yet it also noted that ships bound for non‑Iranian ports would not be impeded.President Trump, in a lengthy social‑media post, framed the operation as a mission to clear mines and prevent Iran from profiting from control of the strait.In a parallel diplomatic move, French President Emmanuel Macron said France and the United Kingdom will convene a conference in the coming days aimed at restoring freedom of navigation, reaffirming that “no diplomatic effort will be spared” to end the US‑Israel conflict over Iran.Nicole Grajewski, an assistant professor at Sciences Po, warned that the US blockade constitutes “more than a minor coercive signal” and effectively marks a resumption of hostilities.Other allies echoed criticism: Spanish Defence Minister Margarita Robles called the plan “makes no sense,” Turkish Foreign Minister Hakan Fidan urged “negotiations with Iran and the swift reopening of the strait,” and Chinese Foreign Ministry spokesman Guo Jiakun emphasized that the strait’s security is “in the common interest of the international community.”Starmer’s stance reflects a careful balancing act—maintaining NATO solidarity while refusing to endorse direct military pressure on Iran—highlighting the complex geopolitics surrounding one of the world’s most crucial maritime corridors.

In a dramatic escalation, police in Noida, a suburb of the Indian capital, deployed tear gas to quell a four-day-old protest by factory workers on Monday. The demonstration had turned violent, with protesters torching vehicles and peltng stones in parts of the satellite city.The police stated that they used "minimum force" to maintain law and order. Narendra Kashyap, a lawmaker from the northern state of Uttar Pradesh, where Noida is located, urged protesters to engage in discussions with the government regarding their demands.Senior police and administrative officials are making persistent efforts to counsel the workers and encourage them to maintain peace and restraint, according to a statement by the Gautam Budh Nagar police.The protest visuals showed dozens of protesters marching on the street, chanting slogans, while security personnel in anti-riot gear looked on. Other images depicted an overturned vehicle with flames and protesters attempting to break through barricades.Noida, one of Asia's largest planned industrial townships, houses thousands of industrial units. The rising living costs globally, exacerbated by the US-Israel conflict with Iran which has impacted fuel supplies, have added to the workers' grievances.In a similar protest in the neighboring state of Haryana last week, the government ordered a 35 percent increase in minimum wages following demonstrations near production units of several car manufacturers.Vinay Mahoti, a 30-year-old worker from Bihar employed at a hosiery company in Noida, highlighted the workers' demands, including fixed duty hours, overtime pay, and adherence to federal government guidelines by companies.

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 United States military confirmed that, beginning at 10 a.m. Eastern Time (14:00 GMT) on April 13, all maritime traffic entering or leaving Iranian ports will be blocked. The directive, issued by U.S. Central Command (CENTCOM), targets vessels of every nation operating in the Gulf and the Gulf of Oman, but explicitly excludes ships merely transiting the Strait of Hormuz to non‑Iranian ports, marking a narrower scope than former President Donald Trump’s broader strait‑wide threat. This decisive action follows the abrupt end of marathon peace talks in Islamabad, where negotiators failed to secure a memorandum of understanding with Tehran. The stalemate has revived fears of renewed hostilities, prompting the U.S. to leverage maritime pressure as a bargaining chip. Financial markets reacted sharply: U.S. crude oil prices surged 8 % to $104.24 per barrel, while the benchmark Brent crude rose 7 % to $102.29. The spikes reflect investor anxiety over potential disruptions to the flow of oil and liquefied natural gas that currently passes through the Strait of Hormuz, a chokepoint responsible for roughly one‑fifth of global energy shipments. Since the February 28 launch of a joint U.S.–Israel operation against Iran, the strait’s traffic has dwindled to a trickle. Iran continues to navigate its own vessels and has allowed limited passage for foreign ships, while discussing a post‑conflict toll system for the waterway. In response to the blockade threat, Iran’s Islamic Revolutionary Guard Corps warned that any U.S. warship attempting to enforce the measure would breach the existing U.S.–Iran ceasefire—set to expire on April 22—and would be "dealt with severely." Iranian Foreign Minister Abbas Araghchi blamed the United States for the diplomatic failure, accusing U.S. negotiators of "shifting the goalposts" when a deal was "just inches away." Academic commentary echoed regional concerns. Zohreh Kharazmi, an associate professor at the University of Tehran, asserted that the United States "is not in a position to dictate" Iranian maritime movements and warned that a prolonged standoff would quickly reveal which side—"the resilience of the Islamic Republic or the resilience of global markets"—would suffer first. While the blockade targets Iranian ports, CENTCOM emphasized that it will not impede freedom of navigation for vessels merely passing through the Strait of Hormuz, a subtle but significant concession aimed at avoiding a full‑scale maritime confrontation.

The article features three brainteasers with their respective solutions. The first puzzle involves a Navy admiral choosing between sending one ship with a P per cent chance of success or two ships each with a P/2 per cent chance of success. The solution reveals that sending one ship is always the better option.The second puzzle introduces two oracles, Randie and Rando, who answer questions differently. Randie responds randomly, while Rando decides to tell the truth or lie. The solution explains how to distinguish between them by asking a specific question that yields the same answer from both a liar and a truthteller.The third puzzle involves a mathematical problem where Johnny calculates 5548-5489 = 59 by incorrectly canceling out digits. A similar calculation XXYZ - XYZW is analyzed, and the solution reveals that Z and W are 8 and 9, respectively.

Tanya Khovanova has long been a leading voice in the world of recreational mathematics, authoring a popular blog and running the Number Gossip site where enthusiasts can inquire about any number.She now debuts her first book, Mathematical Puzzles and Curiosities, co‑written with fellow puzzle‑enthusiasts Ivo David and Yogev Shpilman. Published by World Scientific, the volume offers fresh challenges and inventive twists on classic problems.To give readers a taste, Khovanova selected three puzzles for the Guardian column:1. Battleships – As a naval admiral you must choose between sending a single vessel with a success probability of P % or two vessels each with a P/2 % chance, where the mission succeeds if at least one ship does. Which strategy maximises the odds?2. The Two Oracles – You face two respondents, Randie, who answers randomly, and Rando, who randomly decides to tell the truth or lie before each answer. Is there a method to distinguish them?3. Bad Maths – A student computes 5548 − 5489 as 59, claiming the “548” cancels out. He then experiments with a subtraction of the form XXYZ − XYZW (distinct digits) and observes the result is XW. How many digits in the new expression match those in the original calculation?Solutions to the trio were later posted online (update), but readers were urged to avoid spoilers until the scheduled reveal.Khovanova also reminds fans that she has been curating puzzles for the Guardian every other Monday since 2015 and welcomes new submissions via email.

The 2018 World Cup in Russia served as a high‑profile platform for Vladimir Putin, showcasing his nation and bolstering his personal legitimacy. The tournament was effectively a diplomatic bow to the Kremlin’s ambitions.Fast‑forward to the summer of 2026, and the buildup to the event has taken on a distinctly American flavour, with the competition becoming a backdrop for Donald Trump’s political narrative.The next edition, slated for 2034 in Saudi Arabia, presents a fresh set of challenges. Despite the kingdom’s controversial human‑rights record, the event offers Crown Prince Mohammed bin Salman an opportunity to polish his and the nation’s image. FIFA’s current reluctance to enforce independent oversight of migrant‑worker conditions raises fears that construction could be as deadly as the 2022 Qatar experience.These developments underscore a pressing need to insulate the World Cup from the whims of powerful leaders. One proposed solution is to fragment the tournament—treating it like a monopoly that has become too dominant.Evidence that this approach is feasible already exists: the 2026 World Cup will be co‑hosted by three nations, and the 2030 edition is set to span six countries across three continents (Spain, Portugal, Morocco, Argentina, Paraguay, Uruguay).Building on that, the author suggests a radical redesign: allocate each group stage to a different global city—Paris, Rio de Janeiro, Tokyo, Sydney, Johannesburg, London, the Basque Country, and so on. Knock‑out rounds could be broken into three‑match clusters and scattered worldwide, with the semi‑finals, final, and third‑place match awarded to the highest‑bidding venue.Carbon‑footprint concerns are addressed by noting that teams already travel long distances to a single host nation; distributing groups based on the median distance to participating teams would not significantly increase emissions.Financially, the cost of staging a traditional, single‑host World Cup has ballooned, limiting the pool of viable bidders to those seeking political or economic leverage. A decentralized format would dilute any single leader’s ability—whether Trump, Putin, or the Saudi crown prince—to manipulate the event for personal gain.Decentralisation would still align with FIFA’s stated objectives: expanding the sport’s reach, creating a truly global spectacle, and bringing football closer to fans worldwide.While FIFA claims a fiduciary duty to maximise revenue for its 211 member associations—justifying steep ticket prices and controversial sponsorships—the proposed model could actually enhance revenue by turning each small cluster of matches into premium, high‑value events.Precedent exists in the form of Euro 2020, which, despite being postponed by the pandemic, successfully unfolded across 11 European cities, delivering record‑breaking goal tallies and strong attendance figures.In sum, the most effective way to protect the World Cup’s cultural significance and prevent its exploitation by authoritarian figures may be to deconstruct and disperse it globally, turning a single‑host behemoth into a series of interconnected, locally hosted celebrations of the sport.

Oil prices jumped back above $100 a barrel and global stocks fell after weekend talks between the US and Iran ended without an agreement and Donald Trump imposed a blockade of the Strait of Hormuz. The US president announced the blockade on Sunday, targeting Iranian vessels and ships that have paid a toll to Iran for passage through the strait, in an attempt to choke off the flow of Iranian oil.US Central Command said it would start at 10am ET (5.30pm in Iran and 3pm in the UK), blocking all Iranian Gulf ports and coastal areas, in effect seizing control of maritime traffic in the Strait of Hormuz. The news drove oil and gas prices sharply higher again, after the two-week ceasefire between the US and Iran announced on Wednesday prompted a sharp fall in energy prices, and crude ended the week below the psychological $100 a barrel threshold.Brent crude rose by nearly 7% to $101.74 a barrel on Monday morning, while US crude is up more than 8% to $104.69 a barrel. Gas prices also increased, with the British wholesale gas contract for May soaring by 11.7% to 122.5p a therm. Analysts at JPMorgan Chase said last week they expected oil prices to stay high in the second quarter, above $100 a barrel, before easing in the second half of the year.Most Asian stock markets fell on Monday, with Japan’s Nikkei down 0.7% and Hong Kong’s Hang Seng index losing 1%, while Chinese stocks rose slightly. Sentiment was helped by Beijing’s announcement of a 10-initiative strategy aimed at deepening ties with Taiwan. European stocks also fell, led by airlines including Lufthansa, Wizz Air, easyJet and British Airways parent IAG. The FTSE 100 index in London lost 0.4%, dropping 45 points to 10,555. Germany’s Dax fell 1%, Italy’s FTSE MiB slipped 0.7% and Spain’s Ibex was down 1.1%. With oil and gas prices rising sharply higher, energy companies such as BP and Shell are rallying.Priyanka Sachdeva, senior market analyst at the broker Phillip Nova, said: “In today’s environment, every barrel of risk added to oil markets carries an inflation price tag for the global economy.” She added: “The market reaction underscores a simple but powerful reality: Hormuz risk is not theoretical; it is structural, and it is real.”Interest rate expectations have shifted again; investors now see an 84% chance of two rate increases from the Bank of England this year to tackle rising inflation, up from 60% on Friday. Before the Iran war, the central bank was expected to cut rates. The price of gold fell 0.4% to $4,730.75 an ounce as the blockade fuelled inflation concerns, prompting traders to scale back expectations for Federal Reserve rate cuts this year.

Australian sprint prodigy Gout Gout stunned the athletics community on Sunday at the national championships in Sydney, clocking a legal 19.67 seconds over 200 m. The performance not only smashed his own previous national record of 20.02 seconds but also made him the first Australian to dip below the coveted 20‑second barrier. Gout’s coach and mentor, Di Sheppard, summed up the achievement with a wry grin: “How long’s a piece of string?” – a nod to the seemingly limitless potential the teenager now displays. The run placed Gout ahead of his compatriot Aidan Murphy, who finished a close second, and sparked immediate comparisons with Jamaican legend Usain Bolt. While Bolt’s all‑time best stands at 19.19 seconds (set in 2009), Gout’s 19.67 at the age of 18 already eclipses the Jamaican great’s performance at the same age, according to his camp. Only one other under‑20 athlete has ever posted a faster time – Erriyon Knighton – whose 2022 effort remains unratified after a subsequent ban. James Templeton, the 18‑year‑old’s manager, said the result was “thrilling but not shocking”, recalling that Gout ran 19.84 seconds the previous year with a marginal wind assistance, a time the team always considered his realistic benchmark. Gout himself has been fixated on breaking the sub‑20 mark ever since an illegal run earlier in his career. “I wrote down 19.75 and kept telling myself I’d hit it,” he explained. “Then I hit 19.67 – gotta love it.” Despite the historic run, the teenager shows no intention of slowing down. “I’ve just turned 18, so I definitely think I can go faster,” he said. “It’s about building consistency and there’s no pressure – I’m the only one out there.” Looking ahead, Gout will compete in the under‑20 junior championships this week, opting to skip the 200 m in Queensland and focus on the 100 m. He will then travel overseas for a high‑profile showdown with Olympic champion Noah Lyles over 150 m at the Golden Spike meet in Ostrava, scheduled for June. Should Gout continue his upward trajectory, the athletics world may soon witness a new challenger to Bolt’s long‑standing age‑group record, reshaping expectations for the next generation of sprint talent.
