A violent disturbance at a federal prison sent eight people to the hospital, officials said.
Fights broke out in various parts of the United States Penitentiary Lee in Pennington Gap, Virginia, according to Ed Ross of the Federal Bureau of Prisons. Ross said he "wouldn't characterize it as a riot."
Eight people were transported to Holston Valley Medical Center with range of injuries including stab wounds, broken teeth, and lacerations, hospital spokesman Jim Wozniak told NBC News. Three of the injured were admitted.
A security guard involved in the melee suffered a broken wrist, NBC station WCYB reported.
USP Lee is a high-security prison that holds more than 1,500 inmates, according to the federal bureau of prisons website.
