If you are old enough to remember the great movie “They Shoot Horses, Don’t They?” by Jane Fonda, the movie had nothing to do with horses but the dark forces in Iraq literally using horses.
Read what they used
A horse used for an attack on the American convoy. That has reported by an eye witnesses in the northern city Mosul Wednesday. The insurgents tied the horse with a time bomb to an electricity mast. The bomb exploded when an American convoy drove past. The explosion damaged an army vehicle. The horse was the only victim.
