Five British military horses — including one soaked in blood — sparked chaos in London on Wednesday after they bolted through the streets near Buckingham Palace during the morning rush.

Military horses run loose in London. Multiple horses belonging to the Household Cavalry, part of the British Army, ran loose through the streets of London on Wednesday, injuring at least one person.

A British Army spokesperson was not able to confirm what caused the injury. Megan Morra, who was on her way to work, told the BBC that she saw the striking image of the white horse with a head injury.
