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.

U.S. President Donald Trump launched a scathing attack on Pope Leo XIV on Sunday night, branding the pontiff “weak on crime” and “terrible for foreign policy.” The criticism was posted on Trump’s Truth Social account, where he asserted he does not want a Pope who “criticises the President of the United States.” The outburst appears to be a direct response to recent statements by Pope Leo that condemned the United States’ involvement in the Israel‑Iran conflict. Last week, the Pope issued a rare rebuke of Trump’s threat to eradicate Iranian civilisation, calling the threat “truly unacceptable.” On Sunday, he further urged world leaders to halt ongoing bloodshed, describing the war‑driving mindset as a “delusion of omnipotence.” Trump’s post also referenced the Pope’s earlier questioning of the administration’s hard‑line immigration stance, noting the pontiff’s remark that such policies might not be “pro‑life.” In his response, Trump demanded that Leo “use common sense,” stop “catering to the radical left,” and focus on being a “great Pope, not a politician.” Adding a personal jab, Trump claimed credit for the Vatican’s selection of the first U.S.-born Pope, suggesting the election was intended to curry favour with the White House. “If I wasn’t in the White House, Leo wouldn’t be in the Vatican,” he wrote, before reiterating that he is “not a big fan” of the pontiff, accusing him of “liking crime” and labeling him “very liberal.” The tension echoes past friction between Trump and the Vatican, notably with Pope Francis, who had previously criticized the president’s immigration proposals and questioned his Christian credentials. Despite the diplomatic spat, Pope Leo is scheduled to commence an 11‑day African tour on Monday, beginning with a historic visit to Muslim‑majority Algeria.

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.

Relentless drama unfolded at Aintree on Saturday as I Am Maximus clinched a second Grand National win, joining an exclusive club that includes the legendary Red Rum. The race saw all 34 runners finish without serious injury, underscoring the event’s safety despite its reputation for chaos.The victory marks I Am Maximus as only the third horse since the mid‑1930s to win the National twice, and the first to achieve the feat in non‑consecutive years since Red Rum’s 1974 triumph. Having finished a close second in 2025, the gelding now sits second only to Red Rum in the all‑time Aintree hierarchy.Trainer Willie Mullins admitted the horse’s temperament could spark a bar‑room brawl, recalling a “lairy” incident at a village parade two years ago. “He’d eat you without salt,” Mullins joked, suggesting future photo‑ops may be limited if the horse’s spirit remains untamed.Owner JP McManus, who celebrated a record fourth National win on the day, is expected to aim the champion at next year’s race. If I Am Maximus stays sound, a 2027 return could become one of the season’s marquee storylines.Betting markets reflected the horse’s popularity: a widely reported £100,000 wager at 8‑1 odds was placed before the race, and the gelding entered as the 9‑2 favourite, positioning him among the shortest‑priced favourites in National history. The only cheaper price on record belongs to Poethlyn, who opened at 11‑4 in 1919.Age also played a role. I Am Maximus’s win makes him the first horse older than nine to win since Pineau De Re’s 2014 victory. By comparison, Red Rum captured his third National at age 12 in 1977, but modern course changes have generally favoured younger runners.Unlike Tiger Roll, whose third attempt was thwarted by owner Michael O’Leary’s weight objections, I Am Maximus has already carried top weight to victory, demonstrating a robustness that may appeal to McManus for future campaigns.With the horse’s celebrity status soaring, the racing calendar now enjoys a twelve‑month window to capitalise on his fame, building anticipation for what could be a historic third National appearance.

Rockstar Games, the renowned studio behind the Grand Theft Auto series, has fallen victim to a cyberattack by the hacker group ShinyHunters. The group is demanding a ransom in exchange for not releasing stolen company data, including potentially sensitive information about the highly anticipated Grand Theft Auto VI.The attack, which was first reported on April 13, 2026, involves ShinyHunters threatening to leak data stolen from Rockstar Games' servers operated by a third-party vendor. The group initially set a deadline of April 14, 2026, for the company to enter negotiations.In a chilling message, ShinyHunters warned Rockstar: “Rockstar Games. Your … data was compromised … Pay or leak.” The group has a history of targeting major companies, including Microsoft, Cisco, and Ticketmaster.Rockstar Games has downplayed the impact of the hack, stating that only a “limited amount of non-material company information” was accessed and that there was no impact on players. However, given the high stakes surrounding Grand Theft Auto VI, which has been in development for nearly a decade and is expected to be one of the biggest releases in gaming history, any breach is a serious concern.The ShinyHunters group is linked to The Com, a loose network of cybercriminals, primarily English-speaking individuals aged 16 to 25. This group has been involved in previous high-profile hacks, including the Pornhub breach last year.This incident follows a previous major breach in 2022 when a teenager from the Lapsus$ hacking collective leaked 90 minutes of Grand Theft Auto VI gameplay footage. The hacker, Arion Kurtaj, was sentenced to an indefinite hospital order in 2023. Rockstar reportedly spent $5 million and thousands of hours recovering from that incident.The development costs for Grand Theft Auto VI are estimated to be close to $2 billion, and the game’s tight secrecy makes any data breach particularly damaging. Originally slated for Autumn 2025, the game has been delayed to November 19, 2026.

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.

Tucker Carlson, the former Fox News host, is set to launch his own publishing imprint, Tucker Carlson Books, in partnership with US-based publisher Skyhorse. The imprint aims to provide a platform for books that might otherwise be censored or shut down.Among the initial titles to be published are Russell Brand's How to Become a Christian in Seven Days, described as a "testimony and guide to a timeless, yet zeitgeist-capturing, grounded, yet psychedelic encounter with Christ." Brand is currently facing charges of rape, sexual assault, and indecent assault in the UK, to which he has pleaded not guilty.Another title set to be published is Milo Yiannopoulos's Ex Gay. Yiannopoulos, a controversial "alt-right" commentator, has previously been shunned by publishers due to his contentious views. His 2017 memoir, Dangerous, was canceled by Simon & Schuster after footage surfaced in which he made comments that appeared to condone sex between adult men and underage boys.Carlson, a former Trump supporter and promoter of right-wing conspiracy theories, was reportedly fired from Fox News in 2023. He soon launched his own media company, Tucker Carlson Network, and the imprint is being launched in partnership with this network.Skyhorse publisher Tony Lyons stated that the imprint will give "a platform to things that would, in many cases, be shut down, be censored, and be covered over by propaganda." Carlson emphasized that Lyons is "just looking for books that nobody else will publish."Skyhorse, which was launched in 2006, claims to be one of the fastest-growing independent book publishers in the US. Its previous publications include Woody Allen's memoir Apropos of Nothing and US Secretary of Health and anti-vaccine activist Robert F Kennedy Jr's The Real Anthony Fauci.

A 10-metre long humpback whale that became stranded on a sandbar in the Baltic Sea last month has left experts and the German public in a state of distress. The male whale, which has repeatedly stranded and freed itself, is now stranded once more and in the throes of death.The drama has captivated the country, drawing politicians, shamans, and animal rights activists to the scene. Experts have faced death threats and accusations of worsening the whale's plight, with some calling for the far right to take power.The local mayor has admitted: 'We have all been totally out of our depth.' A leading humpback whale expert has even stopped allowing her name to be quoted in the media, citing the danger of talking about humpback whales in Germany.The whale's condition has rapidly declined due to a fishing net caught in its jaw, weakening it and leading to a loss of direction. The Baltic Sea's low salt levels and shallow waters are not suitable for the whale's survival. Wounds and infections have been detected on its body, with experts describing it as 'very sick.'Despite the emotional public outcry and various rescue suggestions, including using cranes, planes, and inflatable pontoons, authorities have declared the whale beyond saving. The environment minister of Mecklenburg-Vorpommern, Till Backhaus, has pleaded with the public to leave the animal in peace to die, saying it has been one of the most demanding operations of his 27 years in office.
