TOONE, Tenn. (AP) -- A fire is still burning after an explosion that officials say injured six people at a Tennessee plant that makes flares for military aircraft.
Hardeman County Sheriff John Doolen said firefighters at Kilgore Flares Co. in Toone are staying back and letting the fire burn itself out because of the danger there could be another explosion.
Smoke continued to rise from the plant about 75 miles northeast of Memphis long after the explosion happened shortly before noon Tuesday.
Authorities haven't said what caused it but they have ruled out terrorism.
A Memphis hospital said three people were brought there in critical condition and a smaller hospital in Bolivar reported three people there in good condition.
