Seven military horses, one covered in blood, escaped their routine exercise on Horse Guards Parade near Buckingham Palace on Wednesday morning and bolted through central London, leaving four people in need of hospital treatment. The horses were spotted running through the City of London, miles from their starting point, causing damage to vehicles and injuring bystanders. A silver Mercedes van was struck by one of the horses, causing extensive damage and leaving two passengers injured. Witnesses reported seeing the horses running past cars and being pursued by an unmarked police car. The London Ambulance Service received three horse-related calls, including one on Buckingham Palace Road where a person was thrown from a horse. All the horses were eventually accounted for and returned to camp, with several personnel and horses receiving medical attention.
