In London, five horses from the Royal Cavalry Regiment broke free during training in Belgravia, causing chaos on the streets. The horses, riderless and galloping, led to accidents including one hitting a car and another colliding with a tour bus on Buckingham Palace Street. Eyewitnesses described a scene of panic and one injured horse. The London Ambulance Service confirmed four people were hospitalized due to the incident. With assistance from bystanders, the horses were eventually corralled and taken for veterinary care.
