Blast destroys Tennessee munitions plant; 18 missing and feared dead

The explosion at Accurate Energetic Systems about 60 miles (100 km) west of Nashville caused multiple fatalities but officials had yet to determine a death toll as of late Friday night. Humphreys County Sheriff Chris Davis told a press conference the scene was "one of the most devastating situations that I’ve been on in my career,” and that it would take time to determine the cause. Aerial video on WTVF television showed flames and smoke emanating from debris where the building once stood.
