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 are still clinging to hope of finding any of the missing alive, but assume they are deceased, said Humphreys County Sheriff Chris Davis.
As we get into this, we find it even more devastating than we thought initially, he told a news conference.
It's still unclear what caused the explosion at the plant in Bucksnort, Tennessee - roughly 56 miles (90km) south-west of Nashville. The facility specializes in the development and manufacture 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 for half a mile around where the building once stood.
Accurate Energetic Systems (AES), which runs the plant, has suspended its operations.
More than 300 state and local first responders have been searching the site since Friday morning, Sheriff Davis said on Saturday.
The FBI is also at the scene conducting rapid DNA tests to identify victims and notify families.
Local residents described the explosion as terrifying, with shaking houses and widespread panic. The incident has left a significant mark on the Bucksnort community, which relied heavily on the factory for jobs.
The tragedy evokes memories of a previous explosion at the same site in 2014, leaving many in the area grappling with the fallout from this incident.
