Two active bombs from World War 2 were found in Germany. German bomb squads defused both of them successfully after the evacuation of the city of Koblenz that they were found at.  About 45000 people, half population of the city, were moved to safe locations for the diffusion. The big one is an air mine and it had the power to destroy the entire city and the smaller one is a high-density explosive bomb. Bombs were dropped by American and British warplanes during the World War II about 65 years ago. There was a third device, a fog generator, which was destroyed with a controlled detonation. Bomb diffusion is a common task in Germany as there are many missing bombs that appear occasionally and need to be disposed.
