A five-alarm fire destroyed several stores in Williamsburg on Sunday.

The usually bustling Lee Avenue was overwhelmed by thick smoke and raging flames.

Close to 200 firefighters worked to put out the flames for nearly three hours.

The FDNY said the fire started inside one of the many stores at the corner of Lee Avenue and Williamsburg Street East and then spread very quickly to other stores.

Nine firefighters and one EMT were injured in the process, including two who were treated for serious and potentially life-threatening injuries. All of them were in stable condition as of Sunday night.

Fire marshals were trying to determine the cause of the fire as of Sunday and which store it started in.
