A bomb thought to date from WWII exploded in an open field in Limburg-Ahlbach in Hesse on Monday, leaving a wide crater in the ground, as confirmed by police.
Residents heard a loud noise and the earth trembling at around 3:50 am on Monday morning, when the blast occurred. Upon going to the field they discovered a 10-metre wide and four-metre deep hole.
"There was a dreadful banging at four in the morning, I can't describe it but I'll never forget it. It was so strong that the floor underneath me quaked. I looked around and didn't see anything," recalls resident Willi Weisser.
According to local police, the bomb probably ignited itself by a long-term detonator.
On Monday, the area was examined by an explosive ordnance clearance service in order to find possible fragments, a police spokesperson reportedly said.
The unexploded device was among many still thought to be scattered across Germany, 75 years after the end of the Second World War.
