America still has a problem with unexploded Civil War bombs

Live bombs from past conflicts can linger for years, often decades. Or in the case of Civil War bombs, well over a century.

Thousands of unexploded bombs and shells left over from the world wars litter Europe. Berlin officials estimate there’s around 3,000 bombs still buried under the city. Berlin’s growing economy  —  and subsequent construction boom  —  means that unexploded bombs turn up on a regular basis.

Wars always have unintended consequences. And they can still inflict casualties long after the last shot is fired.
