It was fire crews who entered the apartment and found the deceased.
– The fire service spent a long time getting control of the fire. Eventually they got control and then they found a dead person inside the apartment. Relatives have been notified, says operations manager Line Skott in the Oslo police district to NRK.
Three people have inhaled smoke and are being cared for by health personnel.
– It is currently unclear how they are doing, but they were all upbeat and talkative, says Scott.
