This was presumably caused by a stray firework rocket. The professional fire brigade of Saarbrücken was able to prevent the fire from spreading both to the apartment itself and to other apartments and floors.
When the emergency services arrived, a blazing fire on the balcony was visible from afar, and without the quick and professional intervention of the professional fire brigade, a devastating damage could have occurred here. The apartment occupant was not present at the time of the incident. Due to the extinguishing water and smoke, the apartment is currently uninhabitable.
