ROSSVILLE, Ga. (AP) — State fire officials say 35 horses were killed when a fire swept through their stables and another building at a business that raises show horses in northwest Georgia.

Glenn Allen, a spokesman for Georgia's fire marshal, says the fire was reported around 8:30 p.m. Thursday at Happy Valley Farms in Rossville, just south of the Georgia-Tennessee line.

No people were hurt, but the damage was estimated at up to $6 million because of the high value of the horses that perished. Allen described them as show horses, and said that some were worth up to $250,000.

Allen said three buildings -- two stables and a storage facility -- were destroyed in the blaze.

The cause was still under investigation early Friday afternoon.

Rossville is just south of Chattanooga, Tenn.
