German authorities had to evacuate approximately 17,000 residents from the city of Dortmund on Sunday following the discovery of an unexploded 1.8 ton British air bomb.
Sputnik news reports that the 1.8 metric ton British World War II air bomb was found during construction work at the at the site of a pump manufacturer in the city’s Hörde district.
The mine is filled with 1.5 metric tons of explosives, the newspaper said. As the explosive force is several times more powerful than the force of conventional bombs the decision was made to evacuate everyone within 1.5 km of the deadly unexploded ordnance.
The defusing operation was set to occur at 12:00 noon local time, with over 1,000 experts taking part in the operation.
The newspaper said this was the fourth such discovery of a large, unexploded bomb being found in Dortmund since the end of the war.
Two years ago a similar discovery prompted the evacuation of some 45,000 people in the city of Koblenz along the Rhine River.
Estimates suggest that around 20 percent of all World War II bombs failed to explode.
