A German construction worker was killed by a World War II-era bomb when his mechanical digger dislodged it, causing it to explode. Eight other workers were hurt in the explosion, too, and television footage from the scene showed the mangled wreckage of the digger's cab and a nearby hut. The town where the bomb exploded, Euskirchen, is part of German state of North Rhine-Westphalia, the country's most populous state and home to some of its densest industry. The area was pounded by Allied bombs during World War II, and every year throughout the country, hundreds of undetonated wartime bombs are still discovered. Most are successfully detonated; North Rhine-Westphalia said it defused more than 700 of them in 2012.
