No insurance issues. Azeri is not there. These were horses currently racing or being trained to race. A real tragedy. Many of them will never be able to race even if they survived. probably a lot of injuries due to them running around in a panic. Plus the damage to their lungs from the smoke. Horses are fairly delicate creatures. Thoroughbreds are really high strung and easy to injure.
I have profound sadness for all the animals involved.
