Six people are unaccounted for after flames tore through a single home in Pottsville around midnight Sunday.

Firefighters were called to the home at 235 Pierce St. and found heavy fire to the rear of the building and smoke pouring out of the front, Pottsville Fire Chief Todd March said.

March said the six unaccounted for are believed to be four children and two adults.

A state police fire marshal was contacted and was enroute to the scene as crews were still pouring water on the home and searching inside for the missing.

The chief said there is no word on what sparked the fire.

March said due to the amount of fire damage to the building, firefighters have to proceed cautiously when looking for those missing and unaccounted for.

Crews from all Pottsville fire companies responded along with Pottsville-
