No animals were hurt and no buildings damaged when 20 large hay bales caught fire near the Central Livestock yard in West Fargo.

Winds gusting more than 40 mph fanned the flames Sunday evening. Fire departments from West Fargo, Harwood, Mapleton and Horace responded to the scene.

Authorities are still investigating the cause of the fire. West Fargo Fire Chief Dan Fuller says there might have been a flare-up from a waste pile that was recently burned.
