LONDON (AP) — Five military horses spooked by noise from a building site bolted during routine exercises on Wednesday near Buckingham Palace, threw off four riders and caused chaos as they galloped loose through central London streets and collided with vehicles during the busy morning rush hour.
The commotion erupted when the horses from the Household Cavalry, which were conducting an extended exercise for an upcoming military parade, presumably became alarmed by the sound of concrete falling off a moving walkway at a construction site in Belgravia, a swanky neighborhood just to the west of the palace.
