Unexploded ordnance—grenades from World War II—was found on private properties. The owners accidentally unearthed both grenades during earthworks and acted correctly in both cases: they notified the police, who secured the area and called in bomb disposal experts.
The area is now safe and has been checked. According to the bomb disposal experts, there are many calls concerning unexploded ordnance. Shells hidden beneath a layer of soil, like stones, slowly but steadily move upward and emerge at the surface. This happens because water accumulated beneath the shell freezes in winter. The frozen water pushes the shell to the surface.
