A day of world news is marked by grief, accountability and political change. In Uganda, at least 20 children were killed when a school bus returning from a trip to Sipi Falls lost control on a dangerous road and crashed into rocks, prompting a temporary halt to school outings as investigators examine what went wrong. In southwest China, rescuers are still searching through debris after a landslide in Chongqing buried homes, with several people pulled out alive but others feared trapped. In Australia, former Olympic cyclist Rohan Dennis has pleaded guilty to driving while disqualified, deepening the legal fallout from the 2023 crash that killed his wife, Melissa Hoskins. In Britain, a Southampton woman has been jailed for removing the knife used in the murder of teenager Henry Nowak, while at Westminster, Labour’s Andy Burnham has been sworn in as party leader, promising to restore “hope” and confront the populist right.
