Siena Palio horse put down

(ANSA) - Siena, June 29 - A horse was put down Monday after an accident in a rider-less trial run for the Siena Palio on July 2.
    Perciclea, a seven-year-old mare, crashed into a horse in front of her, sustaining critical injuries.
    Horses are often hurt in the famed twice-yearly bareback ride around Siena's central Piazza del Campo, and they are sometimes put down.
    Animal rights activists have been campaigning for years to have the Palio scrapped.
