According to media reports, several people have died following a massive explosion at an ammunition factory in the USA. Others were injured and others are still missing, as the TV channel CNN reported, citing local authorities.
The extent of the damage is unclear. According to TV station ABC News, the explosion occurred on Friday morning around 80 kilometers in the US state of Tennessee on the premises of Accurate Energetic Systems near Bucksnort, southwest of Nashville. The company manufactures and tests explosives.
"Several people are still missing at this time," Sheriff Chris Davis said at a media conference. "Several people have lost their lives." According to first responders, there were further explosions after an initial detonation, which made the operation more difficult and forced emergency services to keep their distance.
The cause of the accident was still unclear. Video footage showed flames and thick smoke rising from a field of debris. Residents reported feeling the shock several kilometers away.
