A gas grill may have contributed.

TAMWORTH, N.H. (AP) – A one-story house in the woods caught fire and collapsed Sunday afternoon.

Fire Chief Jim Bowles said the cause of the fire was related to a propane gas grill that exploded in the flames.

No one was injured.

A couple, friends of the people renting the camp, were inside at the time. They had been cooking on the grill about 45 minutes earlier, Bowles said.

The house was a loss, he said.
