A photo taken at the scene shows firefighters attacking the fire using hoses from the exterior of the structure, which appears to have significant fire and smoke damage.

A call to the Mastic Beach Fire Department was not immediately returned Saturday morning.

No injuries were reported and the cause of the fire remains under investigation, the spokeswoman said.
