Crews battled a fire that destroyed a three-story building in Yonkers Saturday night, and authorities say fireworks might have been to blame.

Firefighters rushed to the scene on Stanley Avenue around 9:30 p.m. 

A total of 12 firefighters were injured, and six families were left homeless, authorities say.

Deputy Chief Joseph Cintrone of the Yonkers Fire Department says the building is a total loss that may need to be torn down.

Cintrone said the blaze may have been started by fireworks and "poor housekeeping outside.” He said fireworks may have ignited rubbish in the back yard.
