Not every bomb dropped or shell fired in a war explodes. Those that don't are called UXO, or unexploded ordnance. UXO can kill long after the war comes to an end.
Nearly half the population of Koblenz, Germany has been evacuated following the discovery of a 3,000-pound bomb dropped by the Royal Air Force into the Rhine during World War II. The evacuees include the residents of seven nursing homes, two hospitals, and a prison. German authorities will attempt to defuse the bomb tomorrow after draining the water from an area of the river surrounding the bomb.
In June 2010, three German explosives technicians were killed in Gottingen when the World War II bomb they were trying to defuse exploded.
UPDATE: The bomb in Koblenz has been successfully defused, along with a smaller one found in the same place. German authorities have also defused a small bomb in Nuremberg after evacuating 200 people there.
