A tourist appeared to feel faint after she was bitten by a King's Guard horse.

The female tourist was bitten on the arm outside the Household Cavalry Museum in London.

The un-named tourist was taking her turn to pose for a picture when the horse bit her on the upper arm and dragged her towards it.

The woman let out a yell in pain and was left cradling her arm.

After a few seconds, she was was seen kneeled over and crouched on the floor.
