Nineteen people are missing after a blast at a military explosives manufacturing facility in Tennessee on Friday.
Humphreys County Sheriff Chris Davis said four or five people were taken to a nearby hospital after the enormous explosion that levelled a factory, and that several are deceased.
"There's nothing to describe, it's gone," he said.
The plant in Bucksnort, Tennessee - roughly 56 miles (90km) south west of Nashville - specialises in the development, manufacture, handling and storage of explosives. The cause of the blast remains unclear.
Aerial video from the scene showed charred debris, smouldering vehicles and little remaining of the facility, which is owned by Accurate Energetic Systems.
