KNOXVILLE — Investigators are trying to determine what caused an explosion at a Knoxville steel mill that injured six workers.

Nearby residents say Thursday night's blast could be heard from blocks away.

Officials with Gerdau Ameristeel Mill say one worker is being treated at a regional burn center. The company says in a statement that five others workers have been treated and released from a local hospital.

The names of the victims have not been released. Officials with the Tennessee Occupational Safety and Health Administration say they are still investigating the cause of the explosion.
