Tech billionaires seem to be doom prepping. Should we all be worried? Mark Zuckerberg is said to have started work on Koolau Ranch, his sprawling 1,400-acre compound on the Hawaiian island of Kauai, as far back as 2014. It is set to include a shelter, complete with its own energy and food supplies, though the carpenters and electricians working on the site were banned from talking about it by non-disclosure agreements, according to a report by Wired magazine. A six-foot wall blocked the project from view of a nearby road.

It was a Monday night in Myanmar's Chang U township in the central Sagaing region, where nearly 100 people had gathered to mark Thadingyut, the festival of the full moon. Some held candles at the event, which doubled as both a celebration and a protest against the military, which seized power in 2021, plunging the country into a bloody civil war. But the celebration soon turned into horror as a motorised paraglider - known locally as a paramotor - flew overhead and dropped bombs onto the crowd. The attack lasted just seven minutes, but at least 26 people died as a result and dozens more were injured. Initially, I thought the lower part of my body had been severed, one 30-year-old who was at the gathering told news agency Reuters.

Rishi Sunak has taken up senior part-time advisor roles at tech giant Microsoft and artificial intelligence start-up Anthropic. The former prime minister has been told he must not lobby ministers on behalf of the companies by the Advisory Committee on Business Appointments (Acoba), an independent watchdog which oversees the activities of former government figures. Sunak - who remains the MP for Richmond and Northallerton - will donate payments for the jobs to a charity he recently founded, the watchdog said. During his premiership, Sunak made tech regulation a significant priority, setting up an AI safety summit in 2023. In letters of advice sent to Sunak by Acoba and published on Thursday, his role at Microsoft was described as providing high-level strategic perspectives on geopolitical trends.

Tesla is being investigated by the US government after reports the firm's self-driving cars had broken traffic laws, including driving on the wrong side of the road and not stopping for red lights. It said it was aware of 58 reports where the electric cars had committed such violations, according to a filing from the National Highway Traffic Safety Administration (NHTSA). An estimated 2.9 million cars equipped with full self-driving tech will fall under the investigation. Tesla, whose boss Elon Musk recently became the world's first half-trillionaire, has been approached for comment. The NHTSA's preliminary evaluation will assess the scope, frequency, and potential safety consequences of the Full Self-Driving (Supervised) mode.

Have Russians set up a military base in my childhood home? It was another busy day at work. Russian forces had attacked my home region of Zaporizhzhia again: a region in the south of Ukraine, split between the Russian invaders, who claim it all as theirs, and the defending Ukrainians. Sitting in my office in central London, I was feeling nostalgic. I decided to take a quick look at the latest satellite images of my childhood village - the poetically titled Verkhnya Krynytsya (or Upper Spring in English), in the Russian-occupied part of the region, just a few kilometres from the front lines.

America's top banker sounds warning on US stock market fall There is a higher risk of a serious fall in US stocks than is currently being reflected in the market, the head of JP Morgan has told the BBC. Jamie Dimon, who leads America's largest bank, said he was far more worried than others about a serious market correction, which he said could come in the next six months to two years. In a rare and wide-ranging interview, the bank boss also said that the US had become a less reliable partner on the world stage. He cautioned he was still a little worried about inflation in the US, but insisted he thought the Federal Reserve would remain independent, despite repeated attacks by the Trump administration on its chair Jerome Powell. Jamie Dimon was in Bournemouth, where he was announcing an investment of about £350m in JP Morgan's campus there, as well as a £3.5m philanthropic investment in local non-profits.
