A 33ft-wide crater has appeared in a cornfield in southern Germany after a Second World War bomb exploded.
Police said the crater was discovered on Sunday afternoon near Limburg, north of Frankfurt, with residents reporting a loud explosion in the early hours of Sunday morning.
Bomb disposal experts believe it was from a 250kg bomb that had been dropped by a plane during the Second World War.
They said it was not unheard of for detonators to decompose to the point that the bomb explodes by itself.
No one was hurt in the blast.
A nearby railway depot had been a target for Allied bombing during the war, and unexploded bombs have previously been found in the area.
Unexploded bombs are still found frequently in both Germany and the UK, more than 70 years after the end of the war, with most discovered by builders digging foundations.
They are unlikely to explode, but the damage they could cause means the bombs are usually taken off-site for a controlled explosion.
In April, a Second World War bomb was detonated in the southern German city of Regensburg.
Despite the controlled explosion, the 250kg bomb still caused nearby windows to shatter.
