The Facebook Live video below was filmed Thursday afternoon, at the moment the Lilac Fire started to engulf the San Luis Rey Downs training facility in Bonsall, California. Trainers were frantically setting the horses loose into the inner track area as the barns started to burn. Reports say that at least 25 horses have perished in the fire, and at least one trainer was injured. Up to 500 horses are normally housed in this facility. Viewer discretion is advised. More: LA Times
