The blaze broke out in one of the houses on Årbyvägen early Friday morning, around 4.30 am. When rescue services arrived, flames were bursting out of the windows, a police spokesman told TT.
Firefighters from several stations combated the flames and evacuated other inhabitants. Rescue services said the fire scene was chaotic and that many people were taken to hospital.
By 6.15 am on Friday morning the fire was still raging out of control on the whole street.
“The whole row-house block is burning. There is nothing left to save,” Björn Sundin, a local police spokesman, told TT.
