Multiple people were dead or missing after a massive blast rocked a US military explosives plant Friday, officials said, sending emergency responders rushing to the site and prompting warnings for the public to avoid the area.
Aerial footage broadcast by US media showed smouldering debris at the blast site in Hickman County, Tennessee, with charred and mangled vehicles strewn across the facility.
"We can confirm there has been an explosion at Accurate Energetic Systems in the Bucksnort area," the local sheriff's office wrote on Facebook.
"Emergency services are currently on the scene working to address the situation," it added.
The mayor's office in Hickman County told AFP that it could not immediately confirm any fatalities or the cause of the explosion.
But Humphreys County Sheriff Chris Davis reported "some" fatalities and added that several people were missing in the "very devastating blast" that engulfed an entire building at the facility.
"We do have several people at this time that are unaccounted for. We are trying to be mindful of families and that situation," Davis told reporters.
"We do have some that are dead. But we're going to go back and, like I say, talk to these families and notify these families."
Davis said authorities had secured the area but warned of the possibility of smaller explosions around the site.
Accurate Energetic Systems, an explosives manufacturer founded in 1980, did not immediately respond to AFP's request for comment.
The company's Facebook page says it manufactures "various high explosive compositions and specialty products" for the US Department of Defence, now rebranded as the Department of War, as well as US industrial markets.
