From BBC News.
Eighteen people are missing after a blast at a military explosives manufacturing facility in Tennessee, US, on Friday.
Initial reports indicated that 19 people were missing, but Humphreys County Sheriff Chris Davis later said one person initially believed to be on site had been located at home.
The plant in Bucksnort, Tennessee – 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.
