Pope's cancer diagnosis leaves Catholics questioning what comes next Image caption, Pope Leo is expected to remain at Rome's Gemelli Hospital for a week as he recovers from surgery Vatican transparency about papal health has come a long way from the secrecy of the past. But that does not mean Catholics were prepared for such seismic news about cancer and removal of a large section of Pope Leo XIV's lung - even after he announced on Sunday that doctors had discovered a nodule. On Tuesday, the 71-year-old was diagnosed with lung adenocarcinoma following 90-minute surgery to remove a lower lobe of his right lung. Part of the shock has, of course, been because there had been few signs until now that concern was needed about any imminent risks to the Pope's health. An Augustinian, he is known to place great importance in good habits, including when it comes to health and fitness, such as weekly games of tennis.

Pope Leo says concerns about AI doom scenarios are not'fake news' Pope Leo gives a news conference on his return flight from France on Monday. ABOARD THE PAPAL FLIGHT - Pope Leo on Monday said concerns that artificial intelligence could destroy the world are not "fake news" and should be taken seriously, in an apparent rebuke of U.S. President Donald Trump. The first U.S. pope, who has warned of the dangers of AI throughout his 16-month papacy, also directly criticized technology CEOs who argued there should be no guardrails on the technology. "I do think that the concerns raised by many of the experts, specialists in AI, should be taken seriously," the pontiff said in a news conference on his flight back to Rome after a four-day trip to France. "I don't think that that is fake news, as some have said."

Pope Leo's Magnifica Humanitas encyclical addresses AI, Catholic social teaching, war, and peace, but its master motif is the irreducible dignity of the human being.

Over the past year, Pope Leo XIV and President Donald Trump have clashed several times in the press, including on the Iran War, nuclear weapons, and immigration. On Monday, Leo potentially opened a new front: AI. Leo's new encyclical --a 42,300-word open letter to the world's 1.4 billion Catholics about preserving dignity in a tech age--never mentions Trump at all.

Pope Leo says AI must be'disarmed' in first major teaching Pope Leo has presented the first major teaching document of his papacy, warning that artificial intelligence needs to be disarmed. The word is strong, I know, but deliberately chosen because this moment needs words capable of attracting attention, the Pope said. Encyclicals are technically letters to Catholic bishops, but over recent decades the missives have become messages to the world from a Pope. While this letter was largely focused on AI, Pope Leo also included one of the strongest, most comprehensive apologies from the Vatican for the Catholic Church's role in slavery. It was impossible not to feel deep sorrow when contemplating the immense suffering and humiliation endured by so many, the Pope wrote, adding that he sincerely asked for pardon in the name of the Church.

The pope's encyclical will address'the protection of the human person in the age of AI', the Vatican says In the first major text of his papacy, Pope Leo will address the rapid rise of artificial intelligence . The Chicago-born pontiff will present the document, known as an encyclical, at the Vatican next week during an event attended by Christopher Olah, the co-founder of Anthropic - a US-based AI firm that has clashed with Donald Trump's administration. The encyclical will address "the protection of the human person in the age of artificial intelligence", the Vatican said on Monday. In a break from tradition, Leo, who was elected pontiff in May last year, will launch the document during a public presentation on 25 May. He will be joined by lay speaker Olah of Anthropic, which is in the middle of a high-profile lawsuit with the Trump administration over the ethics of AI, as well as theologians Anna Rowlands and Léocadie Lushombo.

A day of national mourning is being held in Switzerland on Friday, following a fire which killed 40 young people, mostly teenagers, in a bar in the Crans-Montana ski resort on New Year's Eve. Church bells rang across the country for five minutes, and people stood for a minute's silence in their memory. Firefighters in the resort were applauded as they joined an audience watching the tribute ceremony, which was live-streamed to Crans-Montana from the Swiss city of Martigny. The ceremony saw the leaders of neighbouring countries, including France's Emmanuel Macron, join an audience while speakers, including the Valais canton's president, paid tribute to those who died.

The annual food fight festival ''Els Enfarinats'' has left the Spanish town of Ibi covered in flour and egg shells. Every year participants wear military-style costumes and stage a fake coup using eggs, flour and firecrackers. The eggers go around asking for taxes - donations to charity - from local people and if you don't pay you could end up getting splatted. The festival, held in the province of Alicante, is more than 200 years old and takes place on the 28 December each year to coincide with the Day of the Innocents - Spain's equivalent of April Fools' Day. The French model and actress has died at the age of 91.

Huge plumes of ash and smoke were filmed erupting from Mount Etna, Sicily on 27 December as skiers used the slopes below. Scientists at the Istituto Nazionale di Geofisica e Vulcanologia said volcanic activity at the site, which frequently erupts, had intensified, with craters continuously emitting ash. In response, scientists issued a red Volcano Observatory Notice for Aviation, its highest level, though authorities said flights would continue to operate normally at a nearby airport unless ashfall increased.
