MINDEN, Neb. (AP) — Central Nebraska firefighters say a fire has caused about $80,000 damage to a Minden home.

The fire happened early Friday morning.

The Minden Volunteer Fire Department Chief Tom Brown says the fire was contained to a bedroom in the upper level of the house.

The seven occupants of the home — three adults and four children — were home at the time of the fire but were not injured.

Brown says the cause of the fire is still under investigation, but that the Nebraska State Fire Marshal has determined that it was started unintentionally.

The American Red Cross is helping the residents find shelter and other essentials.
