From that article:
Between 400 and 600 bombs are discovered a year in the state of North Rhine-Westphalia alone, where the heavily industrialized Ruhr region was a major target for Allied bombers.
Three workers were killed and 17 people injured in Berlin in 1994 when a wartime bomb exploded during construction work. In 2003 in the Austrian city of Salzburg, two people were killed while attempting to defuse a 250-kilogram bomb.
