Firefighters are battling a three-alarm blaze in a building at the Suffolk Downs horse race track in Revere.

The fire was reported at about 5:30 p.m. Tuesday. Television news photos showed flames and smokes coming through the roof of one of several large, one-story buildings in the stable area.

No injuries have been reported to people or animals.

A track spokeswoman said she did not immediately have details.

WCVB-TV reported that the fire is in a kitchen area. The station said horses were evacuated from some nearby stables as a precaution.

The track is to begin its live thoroughbred racing season on Saturday.

Mohegan Sun has proposed building a resort casino on the property.
