A student who stabbed his housemate more than 30 times in a masked ambush has changed his murder plea to guilty. Zack Coughlan, 23, attacked Jamie Collins, 21, in an alleyway near the garden of their home on 8 April and then left his body outside for eight hours before calling police. A murder trial had been under way at Bristol Crown Court because Coughlan initially denied the charge, although he did admit killing Collins. He told jurors he stabbed Collins because he feared his housemate would kill him . However, Coughlan, of Cleve Road, Filton, has now changed his plea to guilty and will be sentenced for murder on Wednesday.

Use of tools'may result in the transfer of sensitive data' to China, defense department says The US government on Monday ordered its agencies to stop using artificial intelligence (AI) tools from the Chinese startup DeepSeek, as the countries race for dominance in the fast-moving sector. A notice from the Department of Homeland Security (DHS) announced the ban on products developed by DeepSeek - and tools created using DeepSeek by third parties - saying they must be removed from IT devices. The DHS can issue direction to civilian agencies but not the military or intelligence services. The US defense department did not respond to an AFP request for comment. "DeepSeek's models present multiple threat vectors," said a document attached to Monday's notice.

The UK will deploy RAF Typhoon jets to defend Saudi Arabia in response to escalating Houthi missile and drone attacks, the government has said. The defensive mission will help defend Saudi cities and infrastructure - a move authorised by Prime Minister Andy Burnham - against aerial attacks by the Iran-backed group. It follows Houthi attacks on the Saudi capital Riyadh, as well as on energy sites on the country's coast. These aircraft will operate in a defensive role and will not conduct offensive strikes against the Houthis, Defence Secretary Wes Streeting said in a written statement on Tuesday. The Houthis are locked in a civil war with Yemen's internationally recognised government, which is backed by Saudi Arabia.

Seth Meyers is, unsurprisingly, unimpressed. So gas is over $4 a gallon, inflation's climbing, the Iran war is deadlocked, measles is spreading, AI might kill us, and there's a new strain of drug-resistant, sexually-transmitted diarrhea - sorry to be the bearer of that news - but don't worry everyone, there's going to be a new golf course close to the president's office! says Meyers, blowing a party popper while confetti rains downs.
