"The mine, which de-miners blew up, was found on Wednesday evening by a vacationing German in a zone that was cleared of German mines just after World War II," duty officer Erik Lindholdt told AFP.
He said there had been "no risk" of an accident if someone had stepped on the mine, which was designed for "blowing up tanks." However, he acknowledged that the device was more than 50 years old and could potentially have been dangerous.
Lindholdt also said a phosphorous shell had been found on Thursday on the nearby popular tourist island of Landli, and was also "neutralized" by army experts. He said Danish beaches along the North Sea coast were safe. The Danish Coastal Authority in 2006 launched a clean-up operation of Skallingen's sand dunes and beaches. More than 72,000 mines were laid there by Nazi occupiers in case of an allied invasion.
On Thursday, another phosphorous bomb from World War II was found in a field in Lillestroem, Norway, not far from Oslo, news agency NTB reported. Some 30 residences were evacuated as bomb disposal experts were called to the scene.
