A series of significant fire incidents occurred across Germany and Switzerland in late October 2026. In Germany, reports included the destruction of a warehouse in Aschersleben, an explosion and garage fire in Cologne-Wahn, and a fire at a refugee accommodation in Sittensen. Authorities in Schweinfurt detained a 61-year-old man on suspicion of attempted arson involving residential buildings. In Switzerland, fires destroyed a barn in Beromünster and a farmhouse in Brünisried, while a suspected self-inflicted fire incident was reported at a train station in Ittigen.

By early November 2026, investigations into intentional fires continued in Germany. Police launched an inquiry into a suspected arson incident on the Brocken plateau in Harz National Park. The fire affected roughly 50 square meters of heath vegetation near a botanical facility, but firefighters prevented the flames from spreading further.
