On April 20, 2026 a lone gunman opened fire at the Teotihuacán archaeological complex, one of Mexico’s most visited heritage sites about 40km (30 miles) north of Mexico City. Mexican authorities and multiple news agencies reported a Canadian woman was killed and six other people were injured — four by gunfire and two by falls while fleeing. The shooter later died from a self-inflicted gunshot. Officials recovered a firearm, a knife and ammunition at the scene. Footage circulated showing a man with a pistol on the Pyramid of the Moon and tourists scrambling for cover. Mexico’s president, Claudia Sheinbaum, said federal and state security forces were deployed and that her administration was in contact with the Canadian government. Mexican state security authorities said some of the wounded were Colombian, Russian and Canadian nationals. The site recorded roughly 1.8 million visitors last year; authorities have opened an investigation and tightened security at the complex amid concerns for tourist safety ahead of the 2026 FIFA World Cup, which Mexico will co-host.

Lori Chavez-DeRemer resigned as U.S. Labor Secretary on April 20, 2026, the White House said, stepping down amid a months-long inspector general probe into allegations of professional misconduct. The inquiry, which Reuters and other outlets reported was nearing completion, examined complaints including an alleged affair with a member of her security detail, use of department resources for personal travel, reports of drinking on the job and inappropriate texts sent to young staffers. Several senior aides had already left or been placed on leave as the probe unfolded. Chavez-DeRemer said she will take a private-sector position; White House communications director Steven Cheung praised her record protecting workers. Her deputy, Keith Sonderling, will serve as acting secretary. Chavez-DeRemer, a former one-term congresswoman from Oregon confirmed as labor secretary in March 2025 by a 67-32 Senate vote, had unusual union support when nominated. The inspector general review also touched on messages involving family members and prior complaints that prompted internal probes; police and prosecutors previously declined to bring charges in at least one matter. Her departure follows recent exits of other cabinet officials and leaves questions about leadership and policy continuity at the Labor Department.

King Charles and other senior royals led a series of events in London on April 20–21 to mark what would have been Queen Elizabeth II’s 100th birthday. On April 20 the King and Queen Camilla toured “Queen Elizabeth II: Her Life in Style” at the King’s Gallery, Buckingham Palace — the largest exhibition of the late monarch’s wardrobe with more than 300 items on display. The family viewed design proposals for a national memorial in St James’s Park, including a bronze statue by Martin Jennings and a pavilion and bridge concept by Lord Foster’s team. Princess Anne officially opened the Queen Elizabeth II Garden in Regent’s Park. On April 21 the King released a filmed tribute calling the late sovereign his “darling Mama,” saying her steadiness through change remains an example and that much about today “may have troubled her.” The government-backed Queen Elizabeth Trust was announced with reported initial funding of £40 million to restore community spaces. A Buckingham Palace reception for charities and centenarians concluded the commemorations. Polling cited ahead of the centenary shows continued strong public affection for the late Queen.

Satirical outlet The Onion has struck a licensing agreement to take operational control of Alex Jones’s Infowars brand and website from a court-appointed receiver, a move that must be approved by a Texas judge. Under the proposed deal filed in mid‑April 2026, The Onion’s parent, Global Tetrahedron, would pay $81,000 a month to license Infowars.com and related intellectual property for an initial six months, with an option to renew for another six. The arrangement, supported by some Sandy Hook families who won defamation judgments against Jones, is intended to convert the conspiracy-driven site into a parody and funnel any proceeds toward creditors and victims. Comedian Tim Heidecker has been named creative director as The Onion prepares prototype content. Alex Jones has publicly disputed The Onion’s claim and says he will appeal and continue broadcasting under other arrangements if removed. The licensing plan follows a voided 2024 bankruptcy sale and ongoing liquidation tied to defamation verdicts that left Jones’s operations in receivership.

Desmond Morris, the British zoologist, writer, broadcaster and surrealist painter who wrote the 1967 bestseller The Naked Ape, has died at the age of 98, his son Jason confirmed on April 20, 2026. Born January 24, 1928, Morris combined academic training in zoology at the University of Birmingham and a doctorate in animal behaviour at Oxford with a high-profile media career. He presented ITV’s Zoo Time from the 1950s and later BBC programmes including Life in the Animal World and The Human Zoo, and served as curator of mammals at London Zoo and director at the Institute of Contemporary Arts. The Naked Ape, which argued for an evolutionary view of human behaviour, sold an estimated 18–20 million copies and sparked debate and controversy on science, sex and society. Morris continued to publish books and exhibit his surrealist art for decades, leaving a mixed but enduring legacy as a populariser of behavioural science and a public figure in British cultural life.
