Five military horses broke loose during a rehearsal, leading to a chaotic chain of collisions with vehicles and injuries to four soldiers and three military members along with a civilian cyclist. The horses, including one apparently covered in blood, reportedly became startled by building materials dropped nearby during a rehearsal for an upcoming event. They were eventually rounded up and treated by a veterinarian, and the involved unit, part of the Household Cavalry, was scheduled for an inspection in Hyde Park prior to The King’s Birthday Parade.
