German police say 15,000 residents were evacuated from their homes during the night in a northern town as experts defused a World War II-era bomb. Residents in part of Celle were evacuated Monday evening after the bomb was found on the grounds of an industrial property. Explosives experts defused the 900-kilogram American bomb early Tuesday in an operation that lasted 35 minutes. People were then allowed back into their homes. Though World War II ended more than six decades ago, it is still relatively common for unexploded Allied bombs to be found in Germany.
