Some 10,000 people were forced to evacuate central Potsdam on Wednesday as authorities diffused a 250-kilogram (551 pounds) US aerial bomb from World War II. The bomb was found on Monday on the grounds of a Sparda Bank across from the city’s central station. Authorities cleared an 800-meter radius (roughly a half-mile radius) where the bomb was located. The Potsdam fire department confirmed on its Twitter that the bomb had been diffused at around midday local time. The evacuation affected several businesses and services, including several nursing homes, schools and daycare nurseries. A swimming pool, a large hotel and the regional parliament building also had to be evacuated.
