A week of turmoil for Anthropic culminated in two related developments on March 26–28, 2026. Security researchers discovered nearly 3,000 unpublished assets in an unsecured Anthropic content management system, including a draft blog describing a new model—referred to as Claude Mythos or internally as Capybara—said to be the company’s most capable system yet and to possess “far ahead” cyber offensive capabilities. Fortune and other outlets reported Anthropic confirmed testing the model with early-access customers and warned of unprecedented cybersecurity risks; the leak sent cybersecurity stocks sharply lower (CrowdStrike, Palo Alto Networks and others down roughly 4–7%) and briefly weighed on cryptocurrency prices. At the same time U.S. District Judge Rita Lin granted Anthropic a preliminary injunction blocking the Pentagon’s designation of the company as a “supply chain risk” and a presidential directive to ban its tools from federal use. Lin wrote the measures appeared retaliatory and likely violated Anthropic’s First Amendment and due-process rights; the injunction is stayed for seven days to allow an appeal. The twin episodes have immediate implications for defence procurement, private-sector contractors and how governments handle frontier AI risks.

England kicked off World Cup warm-up preparations at Wembley on March 27, 2026, in a 35-man experimental friendly against Uruguay that combined squad auditions with controversy. Thomas Tuchel rested 11 established starters — including Harry Kane, Declan Rice and Bukayo Saka — while giving debuts to Everton’s James Garner and Manchester City goalkeeper James Trafford. Arsenal’s Ben White was recalled to replace the injured Jarell Quansah; White, who left England’s 2022 World Cup camp, was urged by Tuchel to “clear the air” with teammates. Real Madrid full-back Trent Alexander-Arnold was conspicuously omitted from the selection and posted “Real Madrid and nothing else,” prompting public debate and criticism from former England captain Wayne Rooney. On the pitch Uruguay defender Joaquín Piquerez suffered a stretchered ankle injury early and was replaced by José María Giménez, who took the captain’s armband. England debuted their new 2026 Nike away kit for the match, broadcast widely across free-to-air and streaming services. Tuchel defended his tactical, intensity-focused selections and said late decisions would shape his final World Cup squad for the summer tournament in North America.

Iran-linked hackers claiming the Handala Hack Team said on March 27 they accessed FBI Director Kash Patel’s personal Gmail account and published photographs, a resume and a sample of more than 300 emails online. U.S. officials including the Justice Department and Reuters confirmed the account was compromised; the FBI said the material appears historical and contains no government information and that it has mitigated risks. The Justice Department had seized four domains tied to Handala on March 19 and the State Department is offering up to $10 million through its Rewards for Justice programme for information about the group. Western cyber researchers and U.S. prosecutors have previously tied Handala to Iran’s Ministry of Intelligence and Security and to recent intrusions, including a March attack on medical‑technology firm Stryker. Independent checks by outlets including TechCrunch verified cryptographic email headers for some messages, though the full scope and timing of the breach remain under review. Handala framed the leak as retaliation for the domain seizures and dedicated it to recent naval losses, underscoring cyber operations as part of the wider U.S.–Iran confrontation.

Organizers of the ‘‘No Kings’’ movement expected millions to take part in a third day of nationwide demonstrations on March 28, 2026, with more than 3,000 events registered across all 50 states and parallel rallies in dozens of cities abroad. Leaders said the St. Paul, Minnesota, event would be the flagship, featuring performances by Bruce Springsteen and appearances by Jane Fonda, Joan Baez and Sen. Bernie Sanders. The protests, first held in June 2025 and again in October (organizers estimated about 5 million and 7 million attendees, respectively), are driven by anger over a sweeping immigration enforcement campaign, the killings of two Minnesota residents by federal agents, rising living costs and the U.S.-Israel campaign against Iran. Organizers said two-thirds of events are planned outside major urban centers, including battleground and Republican-leaning counties, underscoring a push to broaden reach ahead of November midterms. The decentralized coalition includes Indivisible, 50501, ACLU and labor groups; the White House dismissed the rallies as politically motivated. Organizers emphasize non-violence and provide legal and safety toolkits; civil liberties groups have issued guidance on protester rights amid concerns about federal policing and possible ICE presence.

The International Olympic Committee on March 26-27, 2026 adopted a new eligibility policy that limits participation in female‑category events at IOC competitions to “biological females” determined by a one‑time SRY gene screen. The rule, announced by IOC president Kirsty Coventry, will apply from the Los Angeles 2028 Games and covers individual and team sports. Athletes who test SRY‑positive would be ineligible for the female category, with narrow exceptions for rare conditions such as complete androgen insensitivity syndrome (CAIS). The IOC said the decision was based on medical expert advice and designed to protect fairness and safety; it noted testing can be done by saliva, cheek swab or blood sample. The move prompted immediate international reaction: U.S. President Donald Trump and several conservative figures welcomed it, while human‑rights groups, many scientists and France’s sports minister called it a “step backwards,” citing ethical, legal and scientific concerns and potential conflicts with national bioethics laws. National Olympic committees in New Zealand and Australia signalled they will implement the policy with care. Observers expect legal challenges, including at the Court of Arbitration for Sport, and debate over testing logistics, costs, privacy and impacts on intersex athletes and grassroots sport.

Nepal police arrested former prime minister K.P. Sharma Oli on March 28, 2026, along with ex‑home minister Ramesh Lekhak, as part of an investigation into a deadly crackdown on youth-led “Gen Z” anti‑corruption protests in September 2025. A government-appointed commission this month recommended prosecuting senior officials for criminal negligence after unrest that left at least 76 people dead and more than 2,000 injured. The panel said it could not conclusively prove an order to shoot was given but found authorities failed to halt hours of firing that killed dozens, including many young demonstrators. The arrests, made a day after rapper‑turned‑politician Balendra (Balen) Shah was sworn in as prime minister and his cabinet moved to implement the commission’s report, led to the detainees being held at the Kathmandu District Police Office; Oli was later transferred to hospital for checks. Lawyers for the former leaders called the detentions improper, saying there was no flight risk. The commission has recommended penalties of up to 10 years in prison for those found culpable.
