The traditional Italian bareback race known as the Palio has claimed another equine life, prompting protests from animal rights activists, according to the Associated Press.

Alghero, a 6-year-old sorrel, was kicked by another horse before the Aug. 16 race. Municipal veterinarians checked the horse over and allowed Alghero to run, however at the first curve he went down with a fractured leg. The horse was euthanized that night, according to the Italian news agency ANSA
