The alarm about the fire came at 03 o'clock towards Monday.
It is a fully developed fire in an apartment on the seventh floor, says Gustaf Sandell, duty officer at the rescue service.
Several people have been evacuated.
We have contact with residents and assessments are made continuously about whether it is best to stay inside or evacuate.
Five fire stations are working with both an internal and external effort. Police and ambulances are also on site.
