Fire officials say two young brothers died in a house fire in southeast Missouri during the weekend.

Reynolds County Sheriff Tom Volner says investigators are still trying to determine the cause of the fire Saturday morning in Bunker.

He says the fire killed a 3-month-old boy and a 2-year-old boy. A woman and three other children made it out of the home safely.

The surviving children were treated for burns and smoke inhalation. Volner says the woman was babysitting the children.

Neighbors told reporters they tried to get to the two boys but couldn’t because of the location of their rooms.
