Police have confirmed that a large crater found in a field in central Germany was caused by the explosion of a World War II bomb early on Sunday.
The explosion left a 10-metre wide and four-metre deep hole after residents in Limburg heard a loud noise and felt the earth shake in the early hours of the morning.
No injuries were reported.
“The crater was examined on Monday by an explosive ordnance clearance service to find possible fragments,” a police spokesman told AFP.
“The area was used for target practice during the Second World War,” he added.
A local government spokesman in the nearby city of Darmstadt told German daily Bild it was believed the bomb had a chemical-based delayed timer which could have finally eroded.
Nearly 75 years after the end of war, Germany remains littered with unexploded ordnance, a legacy of the Allied bombing campaign against Nazi Germany.
Earlier this month, a 100kg US bomb from the war, discovered during building work near a shopping complex, was defused in central Berlin after the evacuation of around 3,000 people.
According to experts, 10% of the millions of bombs dropped on Germany during the conflict did not explode.
