An explosion at a Tennessee military munitions plant left multiple people dead or missing on Friday, a county sheriff said, as first responders said secondary blasts forced rescuers to keep their distance from the burning site.

The blast occurred on Friday at Accurate Energetic Systems, a company that makes and tests explosives.
