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.

How Saudi Arabia's spending spree reached the end of the line Autocratic monarchs once left an echo of their glory in the ruins of the megaprojects they commanded at the peak of their unchallenged power. Those monumental physical traces are to be found in the fertile plains, mountainsides and deserts of the Middle East. But one of their most prominent modern counterparts may only have a digital footprint to leave behind for some of his most ambitious concepts. A decade ago, the Crown Prince of Saudi Arabia Mohammed bin Salman - or MBS as he is widely known - decreed a revisioning of his country that leapt from the realm of science fiction. It was called Vision 2030. Extraordinary monolithic structures were to help bring forth new technological marvels not just for the Kingdom but for the world.

This week, with air raid warnings wailing in the distance, Kyiv held a funeral for two sisters. They had already lost their father who had been fighting on the front line. Their grieving mother is now the family's sole survivor. This is the human cost of the largest sustained Russian aerial assault so far - with 1,500 drones and 56 missiles fired at Ukraine within 48 hours. But the loss of life could have been even higher.

Inside the'kill-zone' on Ukraine's front line, where new weapons have transformed war After 225 days stuck in a front-line foxhole, the Ukrainian infantryman's muscles were so weak he could barely walk. His commanders had tried five times to swap him with another soldier - but they could never reach him. Rotating soldiers on the front line in eastern Ukraine is extremely difficult because of the constant threat of drones. This area near Kostyantynivka is currently one of the most dangerous hotspots and the Ukrainian military admits that Russian forces have reached its outskirts. Known as Kenya, the infantryman took two days to walk 11km (6.8 miles) to get back to his brigade, avoiding mines and hiding from drones to get out.

The United Arab Emirates is investigating the source of a drone strike which triggered a fire near a nuclear power station, officials have said. The country's defence ministry said three drones had entered the UAE from the western border direction on Sunday. While two were intercepted, the third drone struck an electrical generator outside the inner perimeter of the Barakah Nuclear Power Plant in Abu Dhabi. No injuries were reported and there was no impact on radiological safety levels, local authorities said. The country's defence ministry said in a statement that investigations were under way to determine the source of the attacks.

Three people were killed overnight in a large-scale Ukrainian drone attack on the Moscow region, Russian officials have said. A woman died in a house in Khimki, north of the capital, where a person was trapped under rubble, regional governor Andrei Vorobiev said. A man and a woman were killed in the village of Pogorelki. Moscow Mayor Sergei Sobyanin said 12 people were injured in strikes on a city oil refinery. Russia's military said 556 drones were intercepted.

British fighter jets in the Middle East will be equipped with new missile systems to make it cheaper to intercept Iranian drones. Royal Air Force Typhoon jets will be fitted with an Advanced Precision Kill Weapon System (APKWS) to destroy targets more precisely and at a fraction of the price of missiles currently in use, the Ministry of Defence (MoD) announced. Gulf countries and allies in the region have been grappling with how to counter Iran's Shahed drones, which are relatively cheap to make and have been causing considerable damage. During the 2024 conflict between Israel and Iran, the UK was reported to have shot down some drones with missiles worth around £200,000 each. Defence experts have estimated APKWS rockets used by other countries cost around $30,000 (£22,377) each.

The UK has said it will contribute drones, fighter jets and a warship to a joint mission aimed at safeguarding shipping in the Strait of Hormuz. Defence minister John Healey announced the package at a virtual summit of defence ministers on Tuesday. It includes autonomous systems to detect and clear naval mines, drone boats and Typhoon jets for air patrols. More than 40 other nations are involved in the mission, which Healey said would begin when conditions allow. For months Iran has been controlling the Strait of Hormuz - one of the world's busiest oil shipping channels - in retaliation for US and Israeli attacks.

New artificial intelligence (AI) tools and capabilities from Google, Microsoft and xAI will now be tested by the US Department of Commerce before they are released to the public. The tech firms have agreed to voluntarily submit their models for testing through Commerce's Center for AI Standards and Innovation (CAISI). The new pacts are an expansion on agreements by AI companies like OpenAI and Anthropic that were reached during the Biden Administration, and will see AI models from all of the companies evaluated for their capabilities and security. These expanded industry collaborations help us scale our work in the public interest at a critical moment, CAISI's director Chris Fall said. Overall, the evaluations of the AI tools will cover testing, collaborative research and best practice development related to commercial AI systems.
