Wildfires burning across parts of Europe expose and in some cases detonate unexploded ordnance left from World War I and World War II, creating added risks for firefighting and cleanup crews. Multiple outlets report that heat and burning vegetation can bring older munitions to the surface or trigger explosions, with detonations reported in countries including France, Belgium, Germany and the Netherlands.

The reports describe incidents where bomb-disposal teams are dispatched to assess fires near historically fought-over areas, such as forests and battlefields in Belgium’s Limburg/Liège region and other known sites of wartime activity. Some coverage also notes other war-remnant discoveries during drier conditions, including ammunition uncovered in France and ordnance revealed as rivers shrink in parts of Central Europe.

Several articles link the increased threat to climate-driven conditions. They cite periods of drought and heat, alongside earlier rainfall that promotes vegetation growth, and explain that fires and dry landscapes can make it easier for buried weapons to be uncovered or reactivated. While outlets focus on different locations and details, they broadly agree that the underlying danger—unexploded bombs and mines from the world wars—remains present and is becoming more apparent during this wildfire season.
