Ammunition experts rendered an American aerial bomb harmless in Kiel-Oppendorf on Tuesday.
The police announced this on Twitter.
Several streets had been closed to defuse.
Around 2000 residents in Oppendorf on the eastern outskirts of Kiel and in neighboring Schönkirchen had to leave their houses and apartments.
The 500 kilogram bomb from World War II was discovered by experts from the ordnance disposal service last Thursday while evaluating aerial photographs.
