The woman was taken seriously injured to Torsby hospital after the fire.
We have had a very good cooperation with the burn unit at Akademiska sjukhuset in Uppsala, but quite soon we and the relatives realized that it would not be possible to save her life, says chief physician Stephan Axer to SVT News Värmland.
Another person was taken to hospital after the fire, but has now been able to leave the hospital.
The alarm about the fire came during the night against Thursday. About 90 people were evacuated. Nearly 40 of them have not been able to move back to their apartments.
