A 39-year-old father and his 4-year-old son died in a fire in an apartment building in Arnhem in the night from Tuesday to Wednesday. Two other members of the family were injured, reports the Gelderland police.

The mother (36) and daughter (8) were taken to the hospital with injuries, where they are still lying on Wednesday morning. Nothing else has been disclosed about their condition.

The family from Arnhem was visiting the flat on the Gelderseplein, in the south of the Gelderland city. A police spokesperson says that the foursome was found near a stairwell and the elevator, in very bad condition.

The fire raged at the entrance, stairwell and elevator. Part of the residents of the flat were evacuated by the fire brigade. The entrance to the building was destroyed by the fire.
