Around 45-thousand residents or half of the people in the German city are able to return home, after bomb squads successfully defused two bombs that were dropped during World War II. 　　Sixty years ago, this was the scene over Germany. Allied bombs tumble from the sky and onto Nazi positions. It was part of a fearsome bombing campaign, the legacy of which reared its head on Saturday. 　　Officials evacuated 45,000 people from this town - Koblenz - after discovering two unexploded bombs in the Rhine River. Bomb disposal experts were taking no chances with the device, which is powerful enough to potentially knock out a building block. 　　Bomb Disposal Expert, Marco Ofenstein: "We have a British detonator, which was surrounded by water for a long time and the explosives within the detonator react with water over the time, which makes it very dangerous." 　　And the bomb is one of these: a blockbuster. Weighing 1,800 kilograms, they packed enough punch to knock out a factory or dam. 　　During the Second World War, almost 100, 000 of them were dropped on German targets, and many remain undiscovered and unexploded.
