No survivors found after Tennessee explosives plant blast

No survivors are expected to be found after a major explosion at a Tennessee munitions factory on Friday that has left 18 people unaccounted for.

Recovery teams don’t expect to find any of the missing alive, but they are not giving up hope, Humphreys County Sheriff Chris Davis told a news conference on Saturday.

“As we get into this, we find it even more devastating than we thought initially,” Sheriff Davis said.

It’s still unclear what caused the explosion at the plant in Bucksnort, Tennessee – roughly 56 miles (90km) south-west of Nashville. The facility specialises in the development, manufacture, handling and storage of explosives.

Video footage taken on Friday showed fires still burning, charred vehicles, and smoke rising from the razed building. Officials said debris was scattered in a half-mile radius around where the building once stood.

Accurate Energetic Systems, which runs the plant, has suspended its operations.

There was a previous fatal explosion at a unit in the same location in 2014.

Residents of a town about 15 miles (25km) away could hear the explosion, Davis said.

One local resident who lives about 20 minutes away from the facility told the BBC she was sitting at her daughter’s dining table when she heard it.

“All of a sudden we just a heard a loud bang. We didn’t know if it was a gun or what,” she told the BBC.

The Bureau of Alcohol, Tobacco, and Firearms is at the scene helping to investigate the incident.
